Had it for a while and im finally deciding to throw it in....which wire (color's would be nice) do i splice into the pressure switch?

Bruce's directions are pretty straight forward, but all it says for the O2 signal wire is it's USUALLY 2N, but i'd like a definite on that before i start splicing....also once i find the o2 signal wire can i splice my O2 sensor in there and hope for a better reading?

Where are most of you attaching the pressure switch (which vacuum line) and how are you "tuning" the pressure switch and the actual O2 clamp?

Thanks again and i did search but couldn't really find anything as detailed as i like to have before i go cutting wires to my ECU!!!!

I have my pressure switch off my boost gauge line under the dash...

switching at .5psi or so. anything greater and you'll notice the hesitation, anything less and you'll switch during cruise.

2N sounds right, then the ground....it's simple....even I could do it.
