Hey guys,
I did a lot of searching and everything I found pertained to 2gs.

I just installed my MTX-L o2. Everything went fine, I wired the yellow wire to the ecu, (pin 4 - white wire) enabled the narrowband sim, selected the input for LC-1 Wideband, changed the W/B drop down to front o2, and did the open air calibration. When I fire it up, the gauge seems to work but the ecu reading for the o2 is stuck at .80 and the LC1WB value is stuck at 7.4:1.

I am not sure that I tapped the correct pin. Can you look at the attached pic and let me know what you think?

Thanks so much.

You've tapped pin 9.

Here is the pin-out for 91-94 1g:

You appear to have wired the sensor to pin 9. You needed pin 4. White wire with a red stripe. I would recommend soldering the connections and using shrink tube as opposed to using butt splices.

Thanks so much guys. I was hoping it would be something simple.

That was it. Thanks guys.
