a/f gauge question

wassapening guys, i haven't posted in while due to being on leave for a long time. moms place doesnt have the uberweb. as for the question, i've done the research thing on splicing into the signal wire on the o2 connectors, and as always, stealth tt's and vr4's are 99% the same but here it goes: i found on stealth316 the signal wire for a 92 stealth tt is yellow but may differ on newer models and so on and so on. on my 93 vr4 is the signal wire the same yellow wire? if anyone has does the install give me a heads up. thanks a bunch.
yea, im just getting around to installing the gauge after having it for a month now.

I personally wouldn't even bother. It's a narrowband. Get a wideband o2 sensor if you really wanna know what is going on. As far as the color of the wire goes..I'm not sure. But I would think, you could just use Stealth316 to find the ECU connections for each year (http://www.stealth316.com/2-ecu-terminals.htm). Figure out which pin hte wire you want to tap goes to, and check the color at hte ECU.

the ecu pins were my next step, i've had the unit out before and its not that hard so i'll probably just do that. 55 is the front and 56 is the rear. wideband i know, i guess i was feeling cheap when i bought it. i'll just wire this one up for a semi close idea now and the wideband is in the so so near future sometime. thanks for the info vert.

Narrowbands aren't "semi close". They basically tell you if are above or below 14.7 A/F that is all.

That's pretty much how I roll with mine. What's the wideband one tell you? exact numbers?

Yes, generally to 0.1 with a range of about 10:1 to 18:1
