Wiring A/F gauge
Wiring A/F gauge Trying to wire my air fuel ratio gauge up. It's just a narrowband, I need to know which wire to tap into to get a signal for it.
p.s. I know widebands are better..
Thanks for any help

Yes i know its useless. I got it for free. That's why i stated in the first post i know widebands are better. Which purple wire is it? There are like 7 that are going into the pcm.

Sorry I should have been more clear. You need to tap into the purple wire coming off an 02 sensor.

You will have the least amount of resistance closest to the 02 sensor. However, the gauge will still be completely inaccurate unless WOT. I would just send a wire down there if you're persistent on using the narrowband.

dunno in his case but mine....i just spent 5 gino in h/c/i, and n2o....and narrow band in conjuction to my nitrous controller works great due to the fact it also acts as a set point for a a/f lean cut out...so its not soooo pointless
