I've tring to figure out if my T junction trailer wire harness is NS or if there is a problem with the wiring in the truck (89 Sub)
I've a DG, LG, and T wire coming out the left light to the T junction, and get no power on the DG when the left turn signal is on, and a full 13 volts when the right is on. Bulbs on the truck all work correctly.
T is fine when the running lights are on, so is the LG when brakes. How the heck does the signal for the turn signals work for the trailer harness, this has me most confused.
Thanks, AB
