Default 75 wiring issue
Wiring problem! i just put in a new dash wiring harness and connected it to the engine side but im getting no power to the inside, im thinking the engine side hookup is bad possibly what is the name for this part/ harness is it the engine harness or what? also what do you guys think it may be?

In the engine compartment you have an ignition harness and a headlamp harness.

Send Noonie a PM to get involved in your thread,he has a 75 and was just where you are and should be able shed some light. I have a feeling your problem might be the funky way the 75 brings power into the bulkhead with the multiple connections made under the brake booster which also includes the fusible links.

I wouldn't buy anything yet,one wire unplugged will kill the power.
Do you have power at the back of the alternator or any of the large red wires ?
