Converting my engine to ls2 coils and the coils have 2 grounds. 1 ground is for the high current side of the coil and the other is for the trigger signal. My question is do I link the trigger earts togther and wire it to the ecu ground and the high current earth to a location near the coil pack

From my research, one, the first ground in "pin A" gets grounded directly to the engine. The next ground, at "b" gets bunched into the harness star earth point. I am not an expert, but that is how I will be doing mine.

Could you splice them togther then and put them to my star earth point
