This is an unusual request. My current driver is a 2003 TLS, and I'm using my old base 2003 TL as an organ donor for a scratch built hybrid sports car (rear engine ICE, front AC motor) . Currently installing the wiring harness into the project car re-using the 3.2 engine and PCM, lights, power steering, seats, mirrors but will not be using most of the rest of the electronic systems. I have the full shop manual and wiring specs, but it's hard to determine how other systems would impact power train / drivability if missing (not installed). Does anybody know where I could get information about the dependencies programmed into the central PCM? Thanks.
