Bringing back from the dead, have a wiring diagram in front of me, I have no purple wire, Looks like black/white ground, yellow signal, pink ignition, tan IAT sensor, and black which is part of the IAT circuit which grounds in the pcm. Would I just exchange the purple wire in the diagram for the black attached to the IAT? it doesn't look like my IAT has a reference, just sensor and ground.

To convert your wires to the first diagram, Your (A)signal wire is Black, and your (B)ground wire is Tan.

Thanks! That's exactly what I figured.

Resurrecting again...will this work on a 2000 Grand Prix GTP using a LQ4 MAF/IAT? I'm assuming it would, just not sure if the PCMs are similar or not.

what kinda resistor would you want to use to add timing instead of pulling it. I rather be on the safe side and run a nitrous tune, and when im n/a ill add timing. without looking at hp tuners and seeing at what time, how much voltage the knock sensor is picking up, if any, I wouldn't trust just pulling 3 degrees across the board on spray, as timing will vary during the hole shot. maybe im just confusing myself, but I want to do this and I want to get the greatest benefit while being safe, as im going to be running a 200 shot. I know this thread is also old as $#!+
