I'm using a speartech wiring harness and can't figure out for the life of me where the car gets power to the interior from the battery?

Was I suppose to keep my iroc wiring harness?

I'm lost again, starting to think this swap was a bad idea altogether. Nothing is simple lol.

Thanks again for all the help guys.

You cut down the 3rd gen harness to just power and gauges
