Trailer Truck
what is the best way to wire up a trailer harness to a truck?
I have than 4 wire plug that will fit into the plug of the trailer, all I need to know is how to connect the break lights from truck to this wiring plug. it has four colors, black white green yellow. When I look at the wires running to the break lights on the truck I see green/yellow black/red then a very faded one which could have been red maybe then one that is all deffinatly black. I did try to clean the wires to see them better. I know I should take 2 wires per break light and connect each set of two to the plug. I know I have to shave off the insulation off of the proper wires to get the extra wire to run to the plug making a 3 way T. What I wana know is how do I figure out which wires to run? Some one today will get the best answer from me, I just need a thorough answer.
Hook a voltmeter to the vehicle wires one by one and turn the vehicle lights on, push brake pedal etc to exercise each wire and see what function it performs. Maybe a brown wire will be the tail lights that come on when you turn the headlights on and maybe a red wire is left turn and a yellow wire is right turn signal etc. Of course black is ground and green at the trailer may be ground also. Here’s a selection of adapter wiring that comes with instructions:
