7 pin wiring diagram

[derek033091]

im putting on an after market 7 pin trailer harness because the original was taken off and the wires for it are just hanging..however the colors of wires on the after market differ from the ones on the truck..does anyone know what each wire on the truck would go to? any help would be greatly appreciated

Since the wires are already hanging, do a pinout - get a voltmeter (or noid light or whatever), turn on the left blinker, right blinker (and so on) and see which one goes to "hi" voltage.
