Running Wiring For Tail Lights With Active Reverse Lights

Updated 03/08/2017 | Published 03/07/2017

Question:

How to connect the Reverse LED lights wires to the center pin of a 7-way Trailer connector to make it work. I have tried to connect the red wires coming from the LED lights to the center pin but did not work. Is it because its an LED light. What part do I have to add to the line to make it work. Thanks for your kind attention.

You will need a circuit tester, like part # PTW2993, to make sure the c enter pin on the vehicle 7-way trailer connector is active for the reverse lights.

Then make sure the wiring for the lights that are designated for the back-up function on the trailer are run to the correct corresponding pin on the trailer 7-way.

An example for one of our taillight assemblies # STL161RB there are 4-wires at the back of the light. The White wire is for the ground, Black is for the running light, Red is for the brake and turn signal, and the Yellow is for the reverse lights.
