yea I know its narrow ban but hell I'd at least like it to work
I purchased it befer I got tuned on CROME and didnt ever hook it up
the tuner told me that my O2 sensor heater was disabled but I should still geta reading because its like6-8 inches from the turbo

Now there are 4 wires on my 02 sensor

2 whites a black and a gray

Ive tried the gray and black with no luck

how are you guys running your A/F gauges with CROME

hook it in at the ecu. pin d14, it's a solid white wire that's a little bit thicker than all of the other wires.

yep, works just fine!!!!!!!

Going to get mine tuned this week.........

D14 damn where is that ecu schematic for OBD2a cars

and plugging into D14 will work even if the O2 heaters are DISABLED in CROME?

projekteg

it's actually d7 on the obd2 side of the harness, i just assumed obd1 since you said you were running crome. you can either tap it in to d7 on the obd2 harness or d14 on your obd1 conversion harness, it won't make a difference. it won't be a white wire on your conversion harness though, but it's still white on the obd2 harness if that makes any sense.

D7 ok but tell me this since he disabled the O2 sensor with CROME

will it even register even if I tap into D7
and D7 is what the farthest to right plug the smallest one and then count 7 spaces from from left to right?

well I hooked it up to the ecu and so far no signal

the tuner did disable O2 sensor so I guess its not gonna give me any reading at all

AF Gauges are an annoying light show.

why did he disable the heater if you have a 4 wire? just re-enable it.

tiny switch on the power wire kills the light show on long cruises at night.........

but they're still useless
