I received 2 out of three of my AutoMeter 'lunar' guages (got trans temp and A/F, waiting on boost guage), and I have them all installed and ready to hook up the sensor wires. My L is a 2002.

Can someone let me know which of the 02 sensor wires to hook up the Air/Fuel guage? There are 4 wire colors on the 02 sensor - 2 white (one may have a stripe - didn't look really close); one black; and one grey. Which of these wires is the high signal wire?

Thanks for your help - I really appreciate it! Paul

PS. the backlighting on these guages looks great!

 

I do belive that it's pin 87 (red w/black stripe) I am looking for the wire diagram now, I will post it when i find it.

Q

 

I had to talk to three different techs at the local dealership before I found one who knew the answer to this question, which he then verified by checking the tech manual. The black wire from the sensor is the high output signal wire. Some people do connect to the wiring harness where it enters the ECM so that post may be correct also. I chose to connect the lead from the A/F meter to the black wire at the sensor and mine works just fine. Hopes this helps.

 

SouthernStar,

Any pics of your custom paint job?

 

Thanks - this helps a bunch. I would have assumed the black was the ground, so I'm glad I asked. Thanks to all for your help!

 

This is what the hookup looks like:

 

Does anyone know if this is the same for a 99 L? I am going to be installing my ultralites tomorrow.... if I can get the info.
