Please confirm: LS Coil Wiring

I decided to make a new harness and I've finished it. As I'm going through it with a meter I'm second guessing myself.

I wired the coil logic ground to the MS signal ground. (Same as TPS, CLT, and IAT)

Please tell me this is correct as I've loomed the whole harness like an idiot (before testing it 100%)

I will go confirm today on how mine is wired, but I'm fairly certain I followed this picture when throwing mine together. It sounds like you're okay - "signal ground" is indeed where your sensors ground out to.

Some MS models have a test mode where you can test fire your coils/injectors. There is definitely an audible sound when they fire.
