I am trying to install a peformance chip in my pontiac g5 gt?

[CASTRO]

I was trying to install this performance chip in my g5 and in the instructions it says I have to cut the ecu cable that goes to the sensor and put it there but the problem is that I dont know which cable coming out of the ecu is the sensor one, thank you!

there should be a diagram showing what one to cut.

I am a GM drivibility tech for the past 22 yrs and ASE master certified.  Do what you wanna do, but all Im saying is- your asking for trouble.    The next generation  OBDII systems  will create all sorts of problems for you. No starts, SES lights, etc.  Suggest leave it alone- you want more power in a car?  then buy a car thats built for speed

I'm no 'chip' guy, but I think you can do all you need to this computer without cutting any wires.  All it takes is a flash of the ECM from someone who KNOWS WHAT THEY ARE DOING.  Don't try this stuff at home, kiddies!
