97-03 gtp air/fuel ratio gauge

[a98gtp4u]

does any1 know where i hook up the signal wire?

dont even put it in unless its a wideband. my narrowband pulled enough voltage from the signal wire that it was screwing with my fuel trims. unhooked the guage and presto.

:th_scratchhead:I think the question still stands. Where to hook up the signal wire????

 

[TheOtherNick]

Does it say to hook in to the high signal or the low signal wire. High=purple Low=tan

 

[99prixgt]

it goes into the purple.

Yay for a light show!!!

Anywhere you want...the output is useless.

Purple wire on the o2 sensor before the Cat

purple wire, but you should really just leave it off. its seriously a waste of a gauge.

the only way to truely use an afr gauge is to wire it into a completely seperate o2 sensor, or if your not running a cat, wire it to the rear one, and get a wideband. if you get a narrowband and hook it to the front 02 sensor youll seriously never get it tuned. itll pull enough voltage from the signal to the pcm that it will whack out all your fuel trims. its a tuning nightmare plain and simple.
