SOURCE: need wire diagram to hook up trailer lights, truck not factory equipped w/harness,
I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.
SOURCE: wiring diagram from truck to trailer
Get a tester light the type with an alligator clip and a sharp point.
Check each wire for your brake lights,blinkers etc.
i.e. With the blinker light on find the correct wire and splice into it with the corresponding light on the trailer. ( DO NOT CUT THE TRUCKS WIRE)
Remove the covering and twist the plug wires around it and tape or shrink wrap if you can.
Hope this helps
