i recently bought a Redline performance chip for my car. on the 2000 protege the IAT sensor and MAF sensor are one unit. To install this chip i need to connect to the wires that are part of the IAT. I have my HANES manual in front of me and look at my wiring diagram there are two wires that connect directly to the PCM, one wire is a ground, and the other two connect to various sensors before the PCM. Any idea which wires are part of the IAT?

 

check with Redline manufacturer.
