Need help with G-force performance chip installation on

Resolved Question:

How to install G-force performance chip in a 2002 Chevy Avalanche 5.3. It has a 5-wire MAF/IAT sensor connector. I tested the wires with ohm and volt meter. I am getting the same reading on two set of wires the wire colors are black-brown-black/white-red-yellow. Which wire combo do I use?

Welcome! I'm Ron Z!

At the MAF Sensor, the IAT wire colors are:

TAN = IAT Signal ( + )

BLACK = IAT Reference ( - )
