TCM pro compressor install where to get Acc power for relay?

[Tr182md]

I installed the TCM pro single cylinder air compressor and am working on the harness. CAtuned says the harness is specific for the Grenadier but it is way too long. It was coiled up and electrical tape was holding in a loop but if they did not send me the wrong harness i may just redo it and take wire out.

My question is where in the engine bay can i pull a 12v accessory signal? I suppose a running light or something.

Here is the acc wire and the full length of the harness. Also a few install pics.

I thought they had a YouTube install video walking through installation.

Yeah at the end it says that was the hard part now do the electrical. And they just have one picture of wire draped across radiator.

They have War code in box for manual that goes to twin not single and the link on website to install video is for something else. Reading manual and looking at YouTube of someone installing it in a box i got it all figured out except that my “harness” is long enough to go to cabin. There is mention of a cabin harness and an engine bay harness in the manual so maybe i need the other one.

I am handy enough to just cut this up and make a better harness. I was just hoping to save some time and if anyone knew where to get accessory signal. I could hook into the wires provided for ext switches but the harness just asks for the positive.
