I bought an LS7 air intake to replace my LS2 with. I will be getting tuned for the LS7 MAF, but I want to add an IAT sensor. I Have an LS7/3 to LS2 harness converter - so my question is: what color wires do I use for the IAT?
Here are some pics:

 

Mine just plugged in.

Hope you are close to the shop doing the tune, because the car will really run bad.

 

That is a MAP sensor harness... I was talking about MAF. My tuner, Jeremy Formato will be tuning at a do-it-yourself shop here in Miami later this month. I'll do the install myself, then push my car over to the rollers!

 

Sorry.

IAT is built into the MAF

AnywY, terminal B on the LS2 harness is the IAT signal and you'll need to tap into terminal D for voltage

 

Perfect. Thank you.

 

I bought a adapter harness from Caspers Electronics for my Maf upgrade. The LS7 Maf and IAT connectors broken out. Joseph in tech sppt / sales can help.
