You are absolutely right, the ICM needs the ground but I have often questioned if the big cast mounting bracket added or removed heat from the ICM🙃 What I was ruminating about was the coilpack itself, which does not have a grounding requirement in the electrical sense, and maybe I have muddied the water. Not my intention. The ICM has several functions in addition to initiating spark, but the coil(s) have a single purpose, and it does not care which direction it is oriented as long as the connections are in the proper order.
