SOURCE: installing chip and want to double check wiring. Need to find IAT/MAF sensor diagram for 2003 Ford Ranger

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.

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

SOURCE: where do i hook uo a chip with 2 wires to the

DONT DO IT. That is one of those resistor jumper wires thats supposed to give you more horsepower and all. It will mess with the computer and cause other problems. Your car is to new for that stuff and they shouldnt even be sold. Take my advise trust me

SOURCE: I need to know which wires from my air box plug

sorry i do not know the colours off the top of my head, but the IAT it the small 2 wire sensor about halfway up the air duct, and the MAF is the large multi wire connector close to the air filter box. good luck!

I have a 2008 Pontiac G5 I was wanting to install a performance chip to it. It says to connect it to the IAT senor which has 5wires witch wires are for the IAT


The other three wires are for the Mass air flow sensor . That's a new one for me , performance chips or turners are used through the DLC . You program the engine computer . I have no idea what they can do from the intake air temp. sensor .The tan an lit blue wires are for the IAT sensor !

Which are the functional iat sensor wires on an accordd 2008


It all depends on which engine your Accord is equipped with. This is really nice-to-know information when you are asking somebody for help with your engine control circuits.

For the 2.4L engine: At the MAF/IAT sensor connector, Pin #4, GREEN/BLACK is the "sensor ground" and Pin #5, RED/YELLOW is the "sensor input" for the IAT.

For the 3.5L engine: At the MAF/IAT sensor connector, Pin #1 GREEN/YELLOW is the "sensor ground" and Pin #2 RED/YELLOW is the "sensor input" for the IAT.
