i bought a IAT sensor and a 2 bar map which color wires do i need to wire up my IAT sensor and ditch the MAF and weres the best place to put the IAT i was gonna weld it to my intake pipe right off the TB

 

no one

 

I think it's the black and tan wires. Just do a search here; I did and found the info in about 5 minutes.

As far as placement goes, ideally in a location that will not get heat soaked.

 

black and orange same as the wires the sensor comes with

 

I would mount the IAT right after the intercooler. Heatsoak can cause issues with fueling.

 

?? I believe your tuning skills are more advanced than mine but this doesn't make sense. under boost there is probably a small difference from the exit of the intercooler to the TB opening. wouldnt you want to have the temp of air right before the TB? i've been using my MAF for an IAT senors for 2 years now and haven't have a problems. why would you want to trick the PCM into thinking your IAT's are cooler? especially when your timing table goes off of that.

also driving around today i saw temps in the 90+ range and saw no affect to AFR. i was in OL too

 

sweet thanks guys

 

I know a lot of this has been covered, but I will reiterate with my experience.

I put it as close to the throttle body as possible. Welded a bung in and ran it there. Black and Tan wires out of the MAF. My pigtail didn't come color coded, but the hookup doesn't matter as it is simply measuring resistance.

 

It is all relevant really. If you put the sensor by the throttle body, and tune for whatever it reads in that spot, in the end, it will all be the same. I'm horrible at explaining things but if you put it by the intercooler, it will read slightly cooler but the air will still heat up the same amount from the intercooler to the cylinder.

So if you're reading knock when the IAT sensor says 150* in the tb location, you'll still see the same knock if you move it to the intercooler but the IAT will read slightly cooler. The only difference is that the IAT will be less likely to heat soak if it isn't really close to the hot engine like Gadgetized was saying.
