You may have broken wire from the fuse leg to the C1 fuse block connector or from the C1 connector out to the TAC module connector…you will just have to do some wire tracing…the C1 connector is pin D1 as you can see in the wiring diagram.

I have checked from the non power side of the fuse leg to the connector and I have continuity, but no 12V at the connector, I will try and pierce the wire at the connector.

Thanks

Odd that you have continuity but no power at the connector…CHECK THE FUSE !!…visual check not good enough !!

I want to thank you for your help with my issue, turned out to be the fuse block. The fuse showed 12V but the legs it went into apparently were just lose enough it couldn't send the voltage down the wire. I slightly twisted the fuse legs and it started working when it had a tighter fit, never seen that before.

Anything is possible, but I have a feeling this issue will resurface.
