I always knew red was power but there are just so many of them and I had no idea how to trace it from the fuse to the wire... I see a fuse that would work, then I looked at the back of the fuse box and become lost again..when I get home from work today I'll work on it again.

I am also installing an AEM wideband, although in a different configuration, and have a question. How are you running the wires through the firewall? I looked all over and could not find any openings.

I use the AEM to tune vehicles all the time. Yes, you can replace the front stock O2 sensor with the AEM sensor. AEM provides the blue wire to simulate the narrowband O2 voltages (0V-1V), here is what I recommended on the HPTuners forums. This should help you as well, good luck!

As for the signal to the ECM, run extra wire from the blue lead of the AEM to the O2 sensor connector. I forget which one, but having an extra O2 sensor connector will help connecting up. Plus you will not need to cut up your existing one.

Oh, reference this for the narrow band hook up:

HPTuners has a pre-configured input PID for the AEM, you'll see it when you add the E I/O PID. Good luck, you will be happy with it!
