which wire on the air fuel gauge do i tap into. 90 talon n/a 4g63

 

There is a single pin connector that goes to the passenger kick panel, its a little bit up from the floor, but can be seen when you get down there. Its a black connector, and that is the O2 sensor check point, you can just use that lead there for your gauge.

 

Those gauges are worthless cuz 99% of the factory O2 sensors are narrowband (0-1 volt) You need a wideband (0-5 volts) signal to be able to actually monitor whats going on. A narrowband signal will only tell you if the air fuel ratio is lean, correct or rich. By lean or rich I mean leaner or richer than it should be, even if its only .1 more than it should be. Just stop being cheap and buy a wideband O2 sensor if you really care. I got my PLX-M300 for $313 shipped from www.streetrays.com

 

PLX R-500 owns you... best evAr

 

the only connector was one that was closed up and it had three wires coming out of it.if this is the connector which wire gets hooked up,to the gauge.

 

its a single connector its, taped up on the harness. remove some of the electrical tape thats consealing everything.

 

and this wire is also on the n/a harness.

 

dosent matter. Its still an eclipse. they all had these test connectors.

 

yeah i found the wire all the way up there.gauge works good. thanks for everyones help.

 

Welcome.
