Rick, It's my understanding that if you disrupt any of the ECU's info about the position of a rotating part (here I mean engine part like crank angle sensor, TDC sensor, rotor sensor, etc) then the ECU is not gonna get "confused" it's just going to, for saftey's sake, default to killing the engine.
The trick is to do it without throwing a code/CEL.
That being said, I think you're on the right track with the +12v-Ignition thing.
I guess the only way to know for sure is to cut the wire
You could always just solder it back together if it doesn't work right?
Let me know if you find something that works.
Your integra's wiring should be pretty much identical to my civic's (and preludes for that matter)
