Now im implanting type R drivetrain (from Sti4 type R) into STi 3 MY97 wagon. I have problem because electrical wires are braided into main wiring loom. Is there any output from engine ECU or other sensors (except handbrake) which diff ecu really needs?

 

They usually unplug from the loom so you can remove the box- although most of the R's and RA's I've come across that have had centre diff probs are down to the box being removed without unplugging first so they just rip the wires out

sorry if this doesn't help you though... bttt
