Installing LED Vehicle Lighting to Trailer 4-Way Connection  


Recently installed T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector Item # 118449 and tested good with Curt LED Tester on my wifes 2016 Toyota Highlander. I need to connect this to new LED tail lights run, stop, turn I purchased for install in the bumper where the reflectors are below the OEM tail lights. The LED lights have a red and black wire and a separate white connector 2 bladed/2 wire, I think. Separately provided for each is a 4 wire set to black box to red/black. Any idea how to finish this?


Expert Reply:

I can't confirm the fit for each wire function based on color of the LED lights. You can check the lights by connecting the white to the negative terminal of a battery and then connect the other wire to the positive. Once you have the locations of your LED lights based on their wire color, you can connect them to your 4-way who's lights will follow this pattern:
Brown=running/tail light
Green=right side brake and turn
Yellow=left side brake and turn
