My advice Peter, would be to stick with Tarka. Just get any electronics sorted, or even drop to an engine only electronics and run the rest as a normal wiring set up.

I have wondered how feasible this approach is on any modern-ish car. To what extent are things like abs, traction control etc built into the engine ecu. Or immobilisers and alarms not to mention instruments.
I understand the old style 12v wiring system for cars of the 60s / 90s, but I dont understand the canbus interlinked systems
