Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

Hello p klenk.
12 volt battery power is fed to the maf/air temp unit and the various signals processed and sent on to the ECM.
I don't see two wires specific for IAT. Only one in, marked IAT.
I do not see any internal component diagrams nor do I have any data on your chip upgrade.
Whether you can use the air temp out signal I am not sure. Perhaps you can tie in on the air temp output and ground the other lead on your setup.
This type of add on is not too popular here and rarely see them.
I hope yours works well when you get it hooked up.

That is not a chip, it is a resistor in a fancy package. It cost about a dollar to make it. Jet also makes one. All it does is increase the resistance in your IAT circuit so that the PCM thinks the air coming in is colder than it actually is. Since most PCMs will add timing in colder air, you can get a bit of a perforance boost this way. The problem is, modern OBD 2 systems constantly checks itself and sensors. Since the PCM also reads a mass air flow sensor and an oxygen sensor, it eventually sees that there isn't as much air getting in as expected (since colder air is more dense) so it recalibrates the air temperture sensor thinking it is fautly. So, after a couple of days your 'chip' won't make any difference at all and in some cases it can actually cause the service engine light to come on. Also, the claims they make about these chips are unfounded and ridicuouls. Even a real chip or programmer can't expect more than a 15% gain. There is no way this IAT mod will add more than 3% and that will only be the first time you drive it. Try to get your money back and find a real chip or programmer for your car. If you are just bent on putting a resistor in your IAT wire, go get one from Radio Shack for a dollar and pocket the rest of the money.

Hi, below is a picture of your MAF sensor. There are 6 pins visible in the connector. Does your sensor have only 5 pins? Maybe one has broke off. The second picture is the wiring diagram for the MAF/IAT assembly. The IAT is the thermister on the right side of the diagram and uses the pink wire with a black stripe and the orange wire. Is this what you needed?

Vehicles: all computer-controlled internal compustions engines equipped with an IAT (Intake Air Temperature) sensor
Intake Air Temperature (IAT) Sensor
Operation - IAT
This sensor is a resistor based sensor which detects the intake air temperature. According to the intake air temperature reading the ECM/PCM will control the necessary amount of fuel injection.
ECM = Engine Control Module (aka "the car's computer")
PCM = Powertrain Control Module (aka "the car's computer")
