Complete kit bundle containing all necessary components for your project. Professional-grade components designed for reliable performance and long-lasting durability.
Does your trailer have multiple tail lights or does the tail lights seem dim to you? Then it is possible you need a Modulite from Tekonsha. The Tekonsha Modulite product line has power modules designed to virtually eliminates additional electrical draw on the vehicle's tail light circuits. They help to ensures maximum trailer light brightness for your trailer tail lights. It powers the trailer's stop, turn, tail and running lights without overloading your vehicle electrical systems.

Tekonsha is a leading manufacturer of electronic trailer brake controllers, pioneering the category in the 1970s. The lineup spans proportional units such as the Prodigy P3 and Prodigy iD, time-delayed controllers, the wireless Prodigy RF, plus vehicle-specific wiring harnesses, adapters and trailer brake components engineered for smooth, predictable stopping at any speed.
Tekonsha Engineering Company began in 1964 building RV steps and mirrors. Within a few years it had found its real calling, and by the 1970s Tekonsha was pioneering the manufacture of electronic trailer brake controllers, the product category that still defines the brand. More than half a century later it remains the reference name in trailer braking and is part of the Horizon Global group alongside Reese, Draw-Tite, Fulton, Bulldog and Wesbar.
A brake controller is the component that tells a trailer's electric brakes how hard to work and when, and getting that right is the difference between a controlled stop and a shove from behind. Tekonsha builds both major types. Proportional controllers use an internal accelerometer to sense how quickly the tow vehicle is slowing and apply trailer braking to match, so light braking stays light and hard braking is immediate. Time-delayed controllers ramp to a preset output over a fixed interval, a simpler and more economical approach that suits occasional towing.
The current brake controller range covers most of that ground. The Prodigy iD pairs with a phone through Tekonsha's EDGE technology for setup and monitoring, the P3 offers storable settings for multiple trailers and a trilingual colour LED display, the Prodigy P2 adds a dimmable display and boost mode for heavier loads, and the Voyager keeps operation simple and dependable. The Prodigy RF mounts to the trailer itself and controls wirelessly, which suits rental fleets and drivers who swap tow vehicles.
Installation is supported by vehicle-specific brake control harnesses that plug into a factory connector rather than requiring cut-and-splice wiring, along with mounting brackets and adapters. Matched controller bundles pair a unit with the correct harness. Products are tested to meet and often exceed published industry standards.

No. The MODULITE® HD PROTECTOR does not work with multiplex vehicles (BM, BT or BTT). For multiplex vehicles, you must use part 119190 or 119250 instead.
The MODULITE® HD PROTECTOR works with two types of vehicle wiring systems: Type A (2-wire system, where turn and brake functions are combined on one wire and tail light is separate) and Type B (3-wire system, where turn, brake and tail light functions are on separate wires). The correct input wires are determined based on your vehicle's system type.
Required tools are: Phillips Head #2 screwdriver, wire cutters, tester or volt meter, wire strippers/wire crimpers, socket and ratchet set, drill with 3/32" drill bit, and double-sided tape (provided).
Included hardware: 8 cable ties (8.5"), 1 15 AMP fuse, 2 ring terminals, 1 fuse holder, 2 yellow butt connectors, 1 self-tapping screw, 4 blue taps, 1 spade terminal, and 1 double-sided tape. Note: The power wire is not included in part 119147; wiring kit 118150 or 118151 is sold separately.
No. The power wire is not included in part 119147. Wiring kit 118150 or 118151 must be purchased separately.
Yes. You must disconnect and isolate the vehicle's negative battery terminal before beginning installation. Read and follow all warnings and cautions printed on the tow vehicle's battery.
Determine a suitable mounting location for the module. Secure it using the double-sided tape provided. Important: Mount the module so that the epoxy side is pointed towards the ground to prevent water buildup.
Locate a suitable grounding point near the module, such as an existing ground stud. Alternatively, drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Do not drill into the vehicle floor or bed. Clean dirt and rustproofing from the area before connecting. Verify what is behind any surface before drilling to avoid damage to the vehicle or personal injury.
Use 12 gauge wire or larger gauge wire. Connect the module's black wire to this power wire using a butt connector, then route to the vehicle's positive battery terminal using a fuse holder, butt connector, and ring terminal.
No. Do not insert the 15 amp fuse when connecting the power wire to the battery. The fuse is inserted only after all other connections are complete, during the completion step.
Route the power wire carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Secure the harness with the cable ties provided to prevent damage or rattling, avoiding areas that would pinch, cut, or melt the wire.
The blue taps provided are for 16-18 gauge wire only. When splicing, use appropriate gauge wire splices. If your vehicle's input wires are a different gauge, you must use different splices.
Unused input wires may be secured with a spade terminal and attached to ground.
Insert the 15 amp fuse into the fuse holder only after all other installation steps are complete: the module is mounted, grounded, and connected to the battery (without the fuse), the harness is secured with cable ties, and the vehicle's negative battery cable is reconnected.
After inserting the 15 amp fuse and closing the cap, test and verify the installation with a test light or trailer once installed. Test each function independently and in combination.
The 4-flat outputs are: white wire (ground), brown wire (tail), yellow wire (left turn/brake), and green wire (right turn/brake).
For a Type A (2-wire) system where turn and brake functions are combined on one wire and tail light is separate: connect yellow to the vehicle's left turn/brake wire, green to the vehicle's right turn/brake wire, and brown to the vehicle's tail wire. The red brake wire is not used.
For a Type B (3-wire) system where turn, brake, and tail light functions are on separate wires: connect yellow to the vehicle's left turn wire, green to the vehicle's right turn wire, brown to the vehicle's tail wire, and red to the vehicle's brake wire. Use all input wires.
The MODULITE® HD PROTECTOR uses a 15 amp fuse. Do not exceed the stated product amperage rating or the towing manufacturer rating (including in your vehicle owner's manual), as overloading circuits can cause fires.
Yes. The module must be connected to a constant power source. Do not use an alternative power source that is interrupted when the vehicle is off.
When using a volt meter or circuit tester, carefully probe one wire at a time. Do not probe across two wires or across vehicle structure, as this can cause damage or injury.
No. It does not work with multiplex vehicles (BM, BT or BTT). Use part 119190 or 119250 instead.
Yes. Disconnect and isolate the vehicle's negative battery terminal before beginning installation.
Drilling may be required. You can use an existing ground stud, or drill a 3/32" hole for the ground wire. Do not drill into the vehicle floor or bed.
Use 12 gauge wire or larger. The blue taps provided are for 16-18 gauge wire only.
1. Ensure input wires are installed per the Tow Vehicle Inputs Determination findings. 2. Ensure blue taps are installed correctly. 3. Using a tester or volt meter, check for voltage on each input wire near the module. 4. Remove the 15 amp fuse for 10 seconds and repeat the test.
1. Check chassis ground. Ensure the ring terminal is in full contact with bare metal of the vehicle's chassis. 2. Verify the 15 amp fuse is fully inserted into the fuse holder with no breaks. 3. Verify the fuse holder is connected properly to the positive post of the battery. 4. Ensure the module is connected to B+ by checking voltage on either side of the yellow butt connector near the module. 5. Remove the 15 amp fuse for 10 seconds and repeat the test after each step.
