i must be blind... i cannot locate the tach signal wire in the scematic

 

I can't find it either. I wonder if the instrument cluster gets its tach signal through the serial data.

 

it is very possible that PID is serial linked.

i may have to get an inductive adapter for my nitrous window switch and shift light....hmmm

 

I have the pinouts somewhere. I can find them if need be. They're for an 07 LSJ.. I know they have a little bit different PCM's but you can compare the pinouts. I'm too lazy to go upload them here though, if you want them, msg me on facebook or text me for quickest response .. 937-829-5547
