New harness problems
Just finished American auto wire complete harness on my 67 c10. Only thing that works are headlights/high beams and the engine will turn over. Nothing else is working or has power. Iím really discouraged and overwhelmed on where to even start. Any ideas? Thanks guys

Re: New harness problems
Found the first foolish mistake. Did not have any of the fuses installed. I now have turn signals. Still nothing on the dash cluster. Does the connector that plugs into dash cluster only go one way?

Re: New harness problems
I believe the dash cluster plug is 1 way, on mine...72...classic update...harness dash wiring is slightly different for oil pressure vs just lights..Different pages on the instruction sheet...check all your grounds, make sure you have solid clean contact for Frame, cab, front and back sheet metal....should also be a ground clip for dash bezel....also .Welcome aboard.

Grab a test light and start checking things. You'll figure it out

Re: New harness problems
I am days away from starting my install. I hope you figure it out. For me it’s always a simple little thing I over looked.
