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.
