A/F Gauge Install - Honda Prelude Forum

wutangben · 04-05-2002, 07:28 PM

Hey i need to know how you guys hooked up your A/F gauges. I just picked up a Phantom series Autometer A/F gauge for $15

I am still contemplating installing it or selling it, but still need some guidence. Do i wire it into the O2 sensor? the ecu? where exactly at?

thanks

peace

You can wire it off either spot. It is the same wire. Doing it off the ecu is nice because running the wire is easier. I have mine hooked up off the o2 sensor and ran though the firewall and into the car.

ditto same here.. I didn't have the ecu wire diagram when I bought my gauge so I ran it off of the O2 , since I'll be relocating it to my pillar with a volt meter then I'll be moving it to the ecu soon

So far, for my turbo project, I've got the a/f guage, the oil pres guage, and the fuel pres guage. I'm going to mount the fuel pres guage in the engine bay, for obvious reasons. I'll mount 3 on the pillar, and 3 below the head unit (custom setup). Where do I hook the other end of the braided steel oil line up to? I don't have the instructions or diagrams, b/c my friend sold it to me used, from his car.

Thanks,
