i got a 2002 ford f350 DRW. i just installed a 2014 bed (brand new take off) also installed a 2008 rear bumper with parking aid sensors. my truck factory comes with this option. both plugs on my truck (2002) and the bumper (2008) plugs in together. my truck side connector is corroded. with the harness pugged in to the bumper or not i get all 4 sensor codes out of the parking aid module. since my connector is corroded (on the truck 2002) was going to make my own connector. but was wondering if anyone can help me out with wire colors? to match the (bumper 2008). also the plate light also in this connector.
