ok, rdm, if you can confirm the yellow/green and yellow/red wires are useless, then ill just leave them there unused. what is the OPS? i traced the huge ground back up, where should i hook it up to? my ole hacked up sr one had the ground cut off. thanks again.

OPS, oil pressure switch. Trash.

The neutral and 5th gear switches do nothing except trip a CEL if not connected. Do a search, you'll find plenty of threads where I've explained all this. The VSS is only needed for speed, you can theoretically leave every bit of it unhooked, it won't affect anything, but you won't have a speedometer of course. If I was you, and like every car I do a swap on whether it's an SR, RB, or just a 5spd going in, hook up the alternator, starter, and VSS. Leave everything else cut back and taped off. The 5th gear switch only serves to implement the speed/rev limiter, the neutral switch does nothing but tell the ECU when it's in neutral. How often are in neutral when you're driving?
