13BT to 20b NA questions
 

Hey guys, I'm swapping out a 13BT that ran batch fire/wasted spark on MS3pro for a 20B that will be NA. I know I need to run 4 additional injector outputs, and I'll need 3 additional spark outputs going to the IGN1A coils.

I'm pretty sure I know how to wire up those parts, but I'm unsure of what I need to set for the ignition coils and I really dont want to accidentally fry them. Do I set going low or high? one ground goes to the chassis, one goes directly to the engine, and one needs to tie into the 5v ground wire for the sensors?
