Default Any impreza'99 2.5RS owners... please help me!

Hi,
I have difficulty to locate the wires of the IAT (intake air temperature) sensor for my impreza'99 2.5RS. As far as I know, the IAT sensor is combined with the Mass Air Flow Sensor. And I just found four wires coming out from the plug of the Mass Air Flow Meter! The color of the wires are (coming out from the plug starting from left to right) red, red/blue, black, and yellow. Please help to find out which are the wires for the IAT sensor. Thank you very much.

Check out the technical documents section, there's ECU pinouts for your car there, you can get the wire you need from that.

Hope that helps

Bry.

do a search for this, there are like 10 threads for it...
you have a '99, a MAF, so no IAT.. and not to intrude, but why do you need to find it? most threads people make are because they are doing an "ebay mod" which will hurt the car rather then help it...

Yes, I bought the G-Box Performance Module from ebay! It is not the 1.99, 2.99, or 3.99 resistor mod. I looked through the feedback of the seller, and some of his costomers wrote that the G-box does work. So I wanna install it and see if it gains performance or not. Anyways, can someone tell me how to locate the wires for the IAT sensor.
