The car its going into at Sevenstock 21

1. So I finally got my 13B REW mounted in my FC and am now onto mocking up wiring harness (I am rewiring the whole car) and am looking at what ecu to go with. I have a Power Fc that was in a Turbo II that had a gt35 turbo and some other misc things. I am trying to figure out what all i would need to run the Power FC on a REW in an FC chassis.

2. Also wondering how many things i can eliminate because i am wire tucking, so the less things i have to wire too, the less wires i have to tuck

Any input or info is appreciated.
