Help! Air/Fuel Ratio gauge not working?!

[Jace]

Hey,

I just got done installing an Autometer Air/Fuel ratio gauge in my '99 Explorer. I believe that I have it all hooked up right, but it is reading in the red (lean). I do not know why my truck would be leaning out like that. All I have done is exhaust, intake, and plug wires. I have the power and ground wire correct, but the wire I am confused about is the wire to the O2 sensor. I have it hooked up to the orange wire off the O2 sensor. Which in my Hanes manual shows to be the high side. Has anyone installed one of these and have had it working correctly? Any ideas?

Thanks
Jace

I had the same problem. Call up Autometer and ask them which PCM wire to hook into. They'll know the correct one, and then you should get a correct reading. For some reason, sometimes hooking directly to the O2 doesn't work.
