Wiring harnesses

Hey guys, I was inquiring about a wiring service for engine swaps and the guy told me he needed both KA harnesses.

So my question is, are both harnesses in the engine bay? Or do you need to take the dash out or something??

Thanks!!

Hes most likely talking about your main harness that connects to the ECU and the lower harness which runs along the tranny, starter, and alternator.

Awesome, thanks!
