Converter Box to Take Separate Vehicle Wiring and Combine it for Trailer Wiring 4-Way
Question:
For reference, all of the lighting on both the tow vehicle and trailer are LEDS, and they are both outfitted with a 4-wire color-coded pin connection. The turn signal wires on the harness are yellow and green. However, the tow vehicle has separate lights for brakes and indicators and the brake lights are not wired into the trailer harness. Meaning, when I plug the trailer in, only the taillights and turn signals work the brake lights do not light up on the trailer, only on the tow vehicle. Do I simply run wiring between the brake switch wire and the green and yellow wires on the trailer harness? If so, do I need to install any diodes to prevent either the brake lights or blinkers operating where they shouldnt on the tow vehicle? I was told that LEDs have integrated diodes and I shouldnt need to add any. Or do I need to overhaul the wiring harness on the vehicle and get an adapter for the trailer?

Helpful Expert Reply:
So what you need is a converter box to take your separate taillight turn signals on your vehicle and combine them so that the signals can work with your 4-way trailer wiring. For that we have the part # RM-732 that you'd wire to the vehicle wiring and and would combine the stop/turn signals onto one wire like you need.
