Things Change.. Butters is now getting a 392

What made you go with the sublime wiring harness? Does this use a cable throttle or the fly by wire. Still not sure what harness i want to use? So guessing you have to use a computer from then so it by passes all the stuff not connected. Do they lock it or not as if want to go bigger cam and tune etc guessing not an issue?
Is the little module on the loom another fuse box for the harness its self?
