I'm beginning the swap and I'm not sure what needs to happen as far as wiring goes when I go to install.
So here are my questions:
1: Should I pull both harnesses, and get ahold of someone to wire them together?
or
2: Is is possible to simply cut a hole in the firewall to feed the harness from the 3sgte to the ecu (3sgte ecu of course) and would that work with the rest of the car?
Like I said, I've searched and haven't been able to find a solid answer.
Here's a teaser I took a couple days ago.

plenty more pics coming soon. thank you!
