The hitch weight is 51 lbs.
Yes, the Curt 13361 (also designated RRH13361) is designed for 2002-current Dodge Ram pick-ups in 1500, 2500, and 3500 models, in both short bed and long bed configurations.
Yes. The hitch uses different mounting holes depending on bed length. Short bed models use one hole on each side, and long bed models use a different hole on each side. The installation diagram clearly marks which holes to use for each configuration.
Yes. The installation diagram shows that 1500 models use one hole, while 2500 and 3500 models use a different hole. Align the hitch holes to the correct frame holes for your specific model before installation.
The kit includes: 4× 1/2-13 UNC 2" grade 8 bolts (10-10288); 2× 1/2-13 UNC 2-1/4" hex head cap screws (10-10530); 6× 1/2-13 UNC grade 8 serrated flange nuts (20-00062); 2× 1/2" flat washers (30-00133); 2× 0.250" × 1.50" × 3.00" square hole spacers (CM-SP4); 2× 0.250" × 2.13" × 2.13" square hole spacers (CM-SP48); 4× 0.188" × 1.50" × 3.00" round hole spacers (CM-SP34); 2× 0.188" × 1.50" × 2.00" round hole spacers (CM-SP32); and 1× 1/2" fishwire (1_2 FISHWIRE).
No. The installation diagram explicitly states 'NO DRILLING REQUIRED'. The hitch aligns to existing holes in the Dodge Ram frame.
Yes, fishwiring is required. Fishwiring is the process of using a wire (the 1/2" fishwire is included) to guide and slide fasteners into position through access slots in the frame. Specifically, you will fishwire the forward-most carriage bolts into position through the frame access slots.
The manual does not specify whether bumper removal is necessary. However, the installation diagram shows that the rearward-most carriage bolts pass through the bumper beam, suggesting the bumper may need to be removed or repositioned for access. Consult the vehicle service manual or a professional installer for clarification.
1. Raise the hitch into position and align all holes in the hitch to holes in the frame (using the correct holes for your bed length and model). 2. Insert hex bolts through side plates into tow loops, using spacers as needed between hitch and tow loop. Install the outer spacer and flange nut on both sides. 3. Use the included fishwire to slide square hole spacers into place and fishwire the forward-most carriage bolts into position through frame access slots. Insert the rearward-most carriage bolts through the bumper beam and into position on each side. 4. Install remaining hex flange nuts and torque all 1/2" fasteners to 110 lb-ft.
Spacers are used as needed between the hitch and tow loop to ensure proper alignment. The installation diagram shows that square hole spacers are slid into place using the fishwire through the frame rails. Round hole spacers are used at various points as required for proper fit. The exact number and placement of spacers depends on your specific vehicle configuration.
All 1/2" fasteners must be torqued to 110 lb-ft. This applies to the hex bolts, hex head cap screws, and flange nuts used in the installation.
The manual specifies a gross load capacity of 6,000 lbs. trailer weight and 600 lbs. tongue weight when used as a weight-carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The manual specifies a gross load capacity of 10,000 lbs. trailer weight and 1,000 lbs. tongue weight when used as a weight-distribution hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
Do not exceed your vehicle manufacturer's recommended towing capacity. Even though the hitch has rated capacities (6,000 lbs. trailer weight as a weight-carrying hitch, or 10,000 lbs. as a weight-distribution hitch), your Dodge Ram may have a lower maximum towing capacity that must be respected.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify an exact interval, but regular inspection before towing is recommended.
Curt Manufacturing Inc. warrants the product to be free of defects in material and/or workmanship at the time of retail purchase by the original purchaser. If the product is found to be defective, Curt may repair or replace it at their option when returned prepaid with proof of purchase. Warranty is voided by alteration, misuse, or improper installation.
Yes, if you have a 2002-current Dodge Ram 1500, 2500, or 3500 pick-up in short bed or long bed configuration. The hitch uses different mounting holes for each bed length and model.
Torque all 1/2" fasteners to 110 lb-ft.
As a weight-carrying hitch: 6,000 lbs. trailer weight, 600 lbs. tongue weight. As a weight-distribution hitch: 10,000 lbs. trailer weight, 1,000 lbs. tongue weight. Do not exceed your vehicle manufacturer's recommended towing capacity.
The hitch weighs 51 lbs.
The kit includes: one 30 amp auto-resetting circuit breaker, two #10 ring terminals, two 3/8" ring terminals, two 1/2" ring terminals, three 12-10 gauge butt connectors, 10 feet of 10 ga black/white duplex wire, 20 feet of 10 ga blue cross-linked wire, and eight 8.5" cable ties.
Yes, but with a critical difference: these vehicles require the stop signal wire to be spliced to the light green wire on the turn signal harness connector under the dash, not to the brake pedal switch. Do NOT connect to the red wire with green stripe, as serious damage may occur. All other vehicles connect to the brake pedal switch instead.
You will need: a test light, wire stripper/cutter, crimp tool, and 3/8" box end wrench. The test light is used to identify the cold (switched) side of the brake pedal switch.
Yes. The manual cautions to disconnect the tow vehicle's negative battery cable before installation. Reconnect it only in the final step after all wiring is complete.
Mount the 30 amp circuit breaker near the tow vehicle's positive battery terminal. This keeps the power wire run as short as possible and protects the circuit.
Use 10 gauge (10 ga) black wire from the duplex wire included in the kit. Strip 3/8" of insulation from each end. Crimp a #10 ring terminal to the end that attaches to the circuit breaker stud labeled 'BAT', and a 3/8" or 1/2" ring terminal (sized to fit your battery terminal) to the end that attaches to the positive battery terminal.
Feed the 10 ga duplex wire from the brake controller in the cockpit through the firewall into the engine compartment toward the battery. Cut to length as needed. At the battery end, crimp a 3/8" or 1/2" ring terminal to the white wire and a #10 ring terminal to the black wire. Attach the black wire to the circuit breaker stud labeled 'AUX' and tighten the nut with a 3/8" box end wrench.
When passing the duplex wire through the firewall into the engine compartment, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to insulate and protect the wire. The same protection applies when passing the blue cross-linked wire through any sheet metal at the rear of the vehicle.
In the cockpit, attach the black duplex wire to the brake controller's battery wire (typically black) and the white duplex wire to the brake controller's ground wire (typically white). Use either one of the supplied yellow butt connectors or solder the leads together and insulate with heat shrink tubing.
Locate the brake pedal switch on the back side of the vehicle's brake pedal. Use a test light or volt meter to identify the 'cold' or switched side—this terminal will only show power when the brake pedal is depressed. Attach the stop signal wire (typically red) from the brake controller to the cold side of the switch using a wire tap.
Locate the semi-circle turn signal harness connector on the steering column under the dash. It has two rows of wires: a row of four and a row of seven. Attach the stop signal wire (typically red) from the brake controller to the light green wire using a wire tap. Do NOT connect to the red wire with green stripe, as serious damage may occur.
Feed the 10 ga blue cross-linked wire from the brake controller to the trailer connector at the rear of the vehicle, taking up any slack in the wire. When passing through any sheet metal, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to protect the wire.
Attach the blue cross-linked wire to the brake controller's electric brake wire (typically blue) using one of the supplied yellow butt connectors or by soldering and insulating with heat shrink tubing. At the rear of the vehicle, trim any loose blue wire and attach it to the trailer connector's electric brake terminal. Refer to the trailer connector's wiring diagram for the correct terminal location.
Secure any loose wires with the cable ties provided. Connect the black power wire from the circuit breaker to the positive side of the battery. Connect the white ground wire from the brake controller to the negative side of the battery. Finally, reconnect the tow vehicle's negative battery cable to the battery.
The circuit breaker is 30 amps and auto-resetting. It must be mounted near the positive battery terminal and connected directly to the positive battery terminal via the included black 10 gauge wire.
Use a 3/8" box end wrench to tighten the nuts on the circuit breaker studs labeled 'BAT' and 'AUX'.
The kit includes 10 feet of 10 gauge black/white duplex wire for the battery and brake controller connections, and 20 feet of 10 gauge blue cross-linked wire for the electric brake signal to the trailer connector.
Black wire connects to the positive battery and circuit breaker. White wire connects to the brake controller ground and negative battery. Red wire is the stop signal wire from the brake controller. Blue wire is the electric brake signal wire. The manual notes these are 'typically' these colours but recommends confirming with your brake controller documentation.
Yes. You can solder the leads together and insulate with heat shrink tubing as an alternative to using the supplied yellow butt connectors. This applies to connections between the duplex wire and the brake controller wires, and between the blue cross-linked wire and the brake controller.
The black power wire must connect directly to the positive battery terminal via the 30 amp circuit breaker. Connecting to the fuse panel or any other accessory wiring may damage vehicle wiring and cause trailer brake failure. The circuit breaker protects the circuit and must be the only protection between the battery and the brake control system.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness. Serious damage may occur. Connect only to the light green wire. Also, do not connect to the brake pedal switch on these vehicles; use the turn signal harness instead.
The kit is universal but requires an existing trailer connector and brake controller. 1989-1991 Ford E & F-Series with ABS use a different stop signal connection (turn signal harness instead of brake pedal switch). Consult your brake controller documentation for compatibility.
No drilling is required. The kit connects to existing components: the battery, brake controller, brake pedal switch (or turn signal harness on 1989-1991 Ford E & F-Series with ABS), and trailer connector.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness—serious damage may occur. Connect to the light green wire instead, and do not use the brake pedal switch.
Connecting to the fuse panel or accessory wiring may damage vehicle wiring and cause trailer brake failure. The 30 amp circuit breaker must be the only protection between the battery and the brake control system.
Yes, Curt part number 55504 is designed for Dodge Ram 1500, Dodge Ram 2500, and Dodge Ram 3500 models. The installation uses the vehicle's existing taillight wiring harness in positions T3 and T5.
The Curt 55504 is a T-connector trailer wiring harness that taps into your vehicle's existing taillight wiring. It includes a converter box, a 4-flat connector for the trailer, and wiring with yellow and green leads for the driver and passenger sides respectively.
The kit includes a T-connector with yellow and green wires, a black converter box, a white ground wire with eyelet and screw, double-sided tape, cable ties, and a 4-flat connector. You will need a drill with a 3/32" bit if no suitable existing screw is available for grounding.
The manual does not specify whether the battery must be disconnected. Contact Curt Manufacturing or your installer for this safety requirement before beginning work.
Locate the vehicle's taillight wiring harness in positions T3 and T5 under the vehicle. The harness will have connectors similar to those on the T-connector included in the kit.
On the driver's side, separate the vehicle's taillight connectors without damaging the locking tabs. Insert the T-connector end with the yellow wire between the separated connectors, ensuring they are fully inserted with locking tabs in place. Repeat on the passenger's side using the green wire T-connector end.
Route the T-connector end with the green wire under the vehicle to the passenger's side taillight wiring harness. Avoid any location that may pinch or cut the wire during routing.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no existing screw is available, drill a 3/32" hole and secure the white wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage or personal injury.
Drilling is required only if no suitable existing screw with nut is available on the vehicle's frame for grounding the white wire. If drilling is necessary, use a 3/32" drill bit. Always verify that no miscellaneous items are hidden behind or under any surface before drilling to avoid damage and personal injury.
Drill a 3/32" hole if no existing screw is available on the vehicle's frame for grounding the white wire.
Adhere the black converter box to the frame of the vehicle using the double-sided tape provided in the kit.
Secure any loose parts of the T-connector with the cable ties provided in the kit.
Route the 4-flat connector to the center of the vehicle and secure it in a convenient out-of-the-way location.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface. Drilling without checking can cause damage to hidden components and personal injury.
Avoid any location that may pinch or cut the wire when routing the T-connector under the vehicle. Also, do not damage the locking tabs on the vehicle's connectors when separating them.
Yes, the Curt 55504 is designed for Dodge Ram 1500, 2500, and 3500 models.
You need a drill with a 3/32" bit only if no existing screw is available on the vehicle frame for grounding. All other hardware is included.
Drilling is optional and only needed if no existing screw with nut is available on the vehicle frame for the ground wire. If drilling is required, use a 3/32" bit.
Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
The 4-way flat electrical adapter converts a vehicle's 4-way flat trailer connector to other trailer connector types (6-way round, 7-way RV blade, or dual 4-way flat). This allows you to tow trailers with different connector styles. Single-output models (57184, 57183, 57185, 57626, 57676) convert to one connector type; dual-output models (57604, 57624, 57672, 57674, 57102) provide two different connector outputs simultaneously.
Yes. Your vehicle must be equipped with a 4-way flat trailer connector. If your vehicle does not have one, you will need to install a custom wiring harness or other 4-way flat trailer connector before installing this adapter.
Both convert a 4-way flat connector to a 7-way RV blade. The difference is that 57185 includes a mounting bracket, while 57184 does not.
Both convert a 4-way flat connector to a 6-way round. The difference is that 57626 includes a mounting bracket, while 57183 does not.
Curt offers three dual-output models that provide both a 4-way flat and a 7-way RV blade output: part numbers 57672, 57674, and 57102. All three include a mounting bracket.
Curt offers two dual-output models that provide both a 4-way flat and a 6-way round output: part numbers 57604 and 57624. Both include a mounting bracket.
You will need: a 1/8" drill bit, drill, Phillips screwdriver, wire stripper, cutting tool, terminal crimpers, and a test light. The manual also lists three self-tapping screws (#10 - 1/2") as required, though these are not included with the product.
No. The three self-tapping screws (#10 - 1/2") used to attach the mounting bracket are not included and must be purchased separately.
Mount the combination harness in a location on the tow vehicle that is within reach of the trailer's wiring harness and near the center of the vehicle. The mounting bracket (if included) should be attached to the vehicle's bumper or other suitable surface.
Yes. You must drill two 1/8" holes: one for the grounding point and one (or more) for the mounting bracket. Before drilling, you must check for brake lines, fuel lines, wiring and other components that may be hidden behind or under the surface to avoid damage.
No. You must never attach the mounting bracket directly to the hitch by cutting, welding or drilling into the hitch. Mount it to the vehicle's bumper or other suitable surface instead.
The adapter uses four wires: Yellow (auxiliary or back-up lights), Blue (electric brakes), Black (positive power with appropriate inline fuse), and White (ground). All wires except black and white must be connected using 12 gauge (minimum) wire and butt connectors to the appropriate vehicle functions.
The white wire is the ground connection. It must be attached with a ring terminal to a 1/8" hole drilled in a suitable grounding point on the vehicle using a #10 - 1/2" self-tapping screw. This ground connection is required for the harness to work properly. The white wire on the vehicle's 4-way flat connector does not support the ground (-) functions of the combination harness.
Yes. The black wire (positive power) must be connected with an appropriate inline fuse. The manual does not specify the fuse amperage rating.
Use 12 gauge (minimum) wire for all connections. The manual specifies this minimum gauge for the remaining wires (yellow, blue, and black) when connecting to appropriate vehicle functions.
Failing to properly ground the product can cause loss of warranty, overheating and potential fire. The white wire must be securely attached to a clean grounding point using a #10 - 1/2" self-tapping screw in a 1/8" hole. The area must be clean of dirt, debris or undercoating.
Before drilling, you must check for brake lines, fuel lines, wiring and any other components that may be hidden behind or under the surface. Drilling into these components can cause damage and personal injury.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding either rating can cause damage or unsafe operation.
Confirm proper function with a test light or by using a properly functioning trailer. This verifies that all connections are working correctly before towing.
Secure any loose wires using cable ties or equivalent product to prevent them from moving, catching on components, or becoming damaged.
Your vehicle must have a 4-way flat trailer connector. If it does not, you will need to install a custom wiring harness or other 4-way flat connector first. Check the part number table to confirm the adapter converts to the connector type you need.
You must purchase three #10 - 1/2" self-tapping screws for the mounting bracket. You will also need an appropriate inline fuse for the black (positive power) wire; the manual does not specify the amperage.
Yes, you must drill two 1/8" holes: one for grounding and one for the mounting bracket. Before drilling, check for brake lines, fuel lines and wiring behind the surface. Never drill into the hitch.
Yellow = auxiliary/back-up lights; Blue = electric brakes; Black = positive power (needs inline fuse); White = ground (must be properly grounded or warranty is void and fire risk exists). Use 12 gauge minimum wire and butt connectors.
Proper grounding of the white wire is critical. Failing to ground it properly can cause loss of warranty, overheating and fire. The grounding point must be clean of dirt, debris and undercoating.
Test with a test light or by using a properly functioning trailer to confirm all connections work. Secure loose wires with cable ties.
