I'm finishing up wiring the controls for the Hot Rod Air System I'm installing.

I have an EZ Wiring harness and have two black wires;
One marked A/C Power (obvious on how and where to connect that one)
One marked A/C Compressor (not sure where to connect this one??)

Both are black
both are the same gauge
both terminate under the dash

There are no blank terminal lugs on the A/C switches. There is a sperate thermostat control. Would it be attached to the thermostat to kick in the compressor at a certain temp??

Any clues as to where and how it would connect???

i would contact the people that make the harness. after all that should have the answers. don't let them make out like you don't know what your are doing.. just some easy questions.

it sounds like the one marked power should go to the fuse panel marked accessories with the key on. and the other goes to the compressor. which means you will have to extend it. if the other wires are in color i would contact the maker before putting power to these wires.. black is usually ground..

I have an air compressor, when i bought it, it said it could be used with 110 or 220 current. I am wiring it with 110. where it hooks up there are 3 terminals. one has a red wire, 1 with a black wire, and 1 blue. i need to know which is positive, negative, and ground.

I've got a HRA setup that I'm doing in an El Camino. You probably have the same controls that mine has and the wiring layout will be like this.

If you look at the thermostat switch there are 2 blue wires connected, one from the switch and the other long blue wire with a connector on the end. That long blue wire is what connects to the compressor and would be the one replaced by the compressor wire in your new harness.



By the way on my El Camino I did away with the HRA controls and converted the original factory controls to operate the unit.
