    I have two spare switches I want to add that I got from Kenworth for the truck specific. I pulled the dash apart and the truck was not ordered with pre wired spare switches. I found splice block and a power block. Is there way I can wire up the switches using them? no schematic or diagram was provided with the switch. So I’m not sure what pins to wire to. Using these spare switches for watermelon lights. Any help or insight will help. I know Kenworth can do it but I’m trying to save some money.

    Buy a manual or find a wiring diagram online. Do you really want to trust what you read here to not fry your electronics?

    Your CECU module would have to be reprogrammed in order to activate the circuits that these switches would operate. Easy to do with a laptop with a program named "ESA"

    To save on wiring (copper ain't cheap), the 2.1M cabs harness are built with only with what was ordered unlike B cabs that had everything there. You can order overlay harness.
