These were the wiring changes I made to run a DME 7.8 engine management computer from a 2003 Carrera 3.6L. Mine was a race car so I did not hook up the EVAP canister and I removed the catalytic converters and associated SAI system.
I'm in the process of putting a 3.6 on my 2000 boxster, I'm stuck with the wiring on the immobilizer. I have the donor 7.8, immobilizer and key but no start and i have an active immobilizer.
