For my airfuel guage anyone know which wire goes where on the o2 sensor??? I have a auto meter one, and did you have to drill to get it to the fire wall?

im not sure what the wire colors are, but search a/f and in the archives. also try www.vfaq.com im sure there is a lot of info on your question, u just gotta look.

Yes you do have to run it through your fire wall to the computer in the engine bay. As to which wire color it is I can't remember it's been awhile since I installed mine.

Top harness, white wire with black stripe.

Yeap. White wire, black stripe.

make sure you get a good ground. if you don't, it will throw your readings off slightly.. there is a good ECU ground under the engine bay fuse box, to the right of the location of the stock air box.

Do I hook up the purple wire on the auto meter to the white and black with white stripes?? Is that what your trying to say???

Yup, hook it up to the white wire with the black stripe.

As far as going through the firewall, you can pick one of the grommets that some of the other harnesses run or go through the steering column boot.
I ran the vacuum hose for my boost guage through there with no problems. Just make sure it won't rub against or interfere with anything.
