PERRAUD sebastien 0 Report post Posted January 25 Hello, I'm searching information about the wiring of the G4 plug-in Ecu for BMW e36. A friend swap engine from L6 2.8L to L4 2L according to F2000 french rally legislation. So, I'd to build for him a new engine loom In the user guide, there is the a partial wiring: you can find only 1 GND for both ecu supply and sensor signal. In the BMW Electrical manual, sensor GND existing (pin44): but not sure it is used by the Link.... If someone can help me... Thanks Sébastien Quote Share this post Link to post Share on other sites
