Question about Cars & Trucks
The thing I need help figuring out is which wires do I connect to on my MAF/IAT sensor ? Please help me figure this out asap so I don't screw up my car somehow ! Thanks !

SOURCE: IAT and MAF info
I have the same "chip" (really just a resistor). It should be the wire harness that clips into the lower box of the intake. I believe it is a green and a black wire. Just unclip it and slide the end of the resistor into each wire prong. Then tape the heck out of it. I put a rubber cap over mine then electrical tape. Works like a charm

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.

You are probably not going to want to hear this, but the so-called 'performance chip" you are going to install is just a Radio Shack resistor packaged to look like something special-the parts themselves cost less than $1.00, and all it is designed to do is make your engine computer think your engine is not warmed up-it causes the Intake Air Temperature sensor (IAT) to produce a false reading, and your ECU will think the engine is cold (of course, it will not be)-this can cause your engine to run too rich, to not go into closed loop, and it can create many issues with regard to wear, oil deposits and carbon deposits. If you still think you need this, you install it according to the seller's instructions, do not get instructions on how to install it here-because when it doesn't work, you want to go back to the seller and tell them you installed it according to what THEY told you, not someone here. Just trying to help you, honestly, those things are bogus, just google 'performance chip facts and myths'. You have a nice, newer and expensive vehicle, do some research before you damage it.

That is not a chip (it is a 50 cent resistor) and it will void your warranty and likely damage the engine as well.
