Trying to install a performance chip on a 2004 toyota 4 runner. I am trying to find the two wires that run to the ECU from the maf/iat sensor. the chip came with instructions on how to do this using a DVM, but i have three wires that fall with in the parameters that they gave me. Please let me know which two wires are the ones that go to the ECU. Thanks

Hello Jason.

In both the 2.5L and the 3.5L models. the information is the same:

The MAF connector have 5 wires, of which, the IAT is wired to wire number 5 (YELLOW/GREEN).

1- WHITE – QA+
2- RED – VCC2
3- BLACK – QA-
4- RED/GREEN – VCC1
5- YELLOW/GREEN – IAT

So, in this model, an IAT resistor would be connected in line with wire #5. Just open wire #5 or cut it and put one of the cut ends to one lead of the resistor and the other end to the other lead of the resistor.

Good Luck
