TCC and cruise issues.

Hey all,

I have been looking through threads and cant find the answer to my problem.My TCC and Cruise do not work. I have a Dakota Digital dash and a XFI. I have the vss wired directly from the Dakota box to A5 on the XFI harness. I see MPH in the XFI. So the VSS is working. What do I need to wire to make this work?

Quickest way to get to the bottom of the cruise control is to follow the factory guidelines indicated here. It might help sort out the issues with what signals the Cruise Module does or doesn't have from the conversions already done.

As for the TCC solenoid troubleshooting here are the wiring diagrams I could pull out. They might help point you in the right direction anyways.

Thanks much! The connectors are gone but I can find the wires. Definitely a starting point!
