Default '03 EJ20T into 2.5RS - WIRING Q's.

The project is coming along very well and slowly everything is installed in place. I do not have a lot of time but only 4 hours a day to work on the car, and I am actually dragging it. So, so far all major engine parts are in. Now, for the electrical wiring work:

1. I have all harnesses that I need pre-fabbed for me from the guy who sold me the engine.

2. If I understand correctly, you just splice the ECU wiring harness of the WRX on to the ECU harness of the RS (not every wire, but wires that are on the chassis need to be wired on the WRX ECU,right?). Am I correct on this or do I need to splice other wires at other locations? (Except the fuel pump controller).

Thanks for all your help guys. Oh by the way, I do have the SMJ plugs/wiring harnesses.
