What is the Wiring Color Code for a 4 Pole Flat


What is the normal wiring color code to the corresponding terminals for a four flat?


Expert Reply:

Below I have posted a link to the trailer wiring page that has a color code chart on it.

Brown = taillights
Yellow = left turn/brake
Green = right turn/brake
White = ground wire

To confirm you have the correct connections you can use a circuit tester like the Quickee Tester, # 3808, and match the wiring from the vehicle with your 4 flat.
