I know. I asked and you said. If you knew what a siemens ecu was, you know that you dont have one.
um, wires...
knock sensor? (Not sure) 1 wire
Boost solonoid (2 wires)
help me someone... I think 6 wires would cover it.
Personally if I was doing it, id run the extra wires. Because in the jumbuck the gsr loom creates issues with reverse lights and alarm and one other thing I cant remember.
