Just for the record. The wiring isn't that complicated - once you have simplified it. If you have ECU Doctors or someone similar modify the ECU so that it is no longer reliant on the immobilized for GO signal it is almost a self sufficient package between ECU and engine. When we build specBoxsters we eliminate 40lbs of unused wire and what you are left with is a pretty simple harness. There is still a lot going on between ECU and Engine but most of the sensors it relys on are in the engine. I think the only forward connections from there are the instruments the OBII and a couple of speed sensors. Anyone with half a brain and a wiring diagram could figure out what is needed and what is not. Even if you leave the immobilized in place (which we must do for SpecBox) there is only about 6 wires actually required to feed the ECU coming from the immobilizer. It looks daunting but it really isn't. The first time I did it I just unravelled the wiring harness while still connected to everything and started removing things that I knew I wasn't going to need. If you could unplug it and the car still ran then you knew every wire from there to the ECU (or immobilizer) was not required - and on it goes.
