Hello, New here and am looking for a radio wiring diagram for a 2020 Peterbilt 579, Vin LD704424 I need to be able to identify Power, ground etc., as the OEM plug does not match traditional radio wires. OEM harness has 2 yellows, green, and the black power is a separate black plugged into its own power port on the Delphi radio.
Are you putting an aftermarket radio in place of the factory radio? If so Raney’s.com or Amazon may have the adapter to help you. I did this years ago and the adapter came with the wiring diagram I needed to properly hook it to the truck wiring harness without cutting any wires. Something similar to one in the picture is what I used by soldering it to the plug that came with my new stereo. The adapter plugged directly in to the trucks wiring harness when the OEM radio was disconnected.
I appreciate the info. I overnighted one of those harnesses. Greatly appreciate the quick response. That should solve it
