Hi, I am currently remaking my engine harness and also upgrading to Audi R8 coils at the same time. The Audi R8 coils have two ground pins, a sensor and a supply ground. Supply ground goes to the engine but will I just connect sensor ground to chassis? From online response, some have connected to ground and others to the engine but I want to properly ground them. Is it wise to connect sensor ground from the R8 coils to the ground of the igniter chip? If anyone has a wiring diagram (I have looked online and not been very successful) for the Audi R8 coils to SR20 engine, that would be great. Thanks.
