Wire Colors and Functions on 4-Pole Trailer Wiring
Question:
which color wires go to the clearance lights? thanks!!!
asked by: Jason R
Helpful Expert Reply:
In 4-pole trailer wiring like # 16-4B-1 clearance lights (and tail lights) will connect to the brown wire.
The 4-pole format's wire color/function arrangement is as follows:
WHITE wire is ground
YELLOW wire is LEFT stop and turn
GREEN wire is RIGHT stop and turn
BROWN wire is running/clearance lights
If you like you can refer to the linked article on wiring for more details. These wire color and function assignments are always the same in 4-pole wiring, including items like
# A35W42B Wishbone harness with dual running light wires
# HM48192 Quick-Fix Replacement 4-Way Trailer plug
# HM48148 Easy-Pull 4-Pole Flat Extension
