Default Air/fuel gauge hot wire

What wire do you tie into on the Oxygen sensor when running the hot wire from the a/f gauge?

Also, I don't believe that I have to buy anything additional to get it workin.. Pacesetter headers with o2 sensors and autometer a/f gauge. Sound about right??

Should just be a plug that plugs into the o2 isn't it?

uhh are you trying to tie an A/F gauge into a narrowband (stock) o2 sensor? Not going to work how you want it to. You need an actual wideband controller with o2 sensor that you drill and weld another bung to the headers behind the existing narrowband o2s to get your readings

I thought you could tap into the o2 wires in the PCM?

It's just a narrow band a/f gauge. I thought you just simply spliced the 2 wires together. I didn't think you had to tap for a new o2..

why even run a narrowband though its pointless.. I'm not sure how to splice a narrowband in but you probably just splice into the o2 sensor itself and ground the other
