Question About Air/Fuel Gauge
 
Well i understand the positive/negative wires and the ignition wires. But what wires do i tap into for the actual sensor? I have 2 sensor to pick from but, which wires do i tap? Some help would be nice.

Pin 60 on the ECU.

Pink w/ light blue wire..

Under the passenger front carpet...

Yea i know that i can use the ecu...I would rather not for warranty reasons. So what wires on the actual O2's do i use?

Yea....i got that set of instructions. But WHICH wires do i tap? There are 3 wires. Which one do i go with. Not trying to be a asshole. Just want to get the thing installed.

you want to hook it to the first o2 sensor, if you are going to connect it there. there should be two black wires for the heater part, and either a blue or white wire for the signal.

Ok that helps out a bit.....now do i have to tap into all 3 wires or just one?

If you want the signal, then I would say only one.

IMPACT April-14th-2003 10:17 PM

ok then....which one do i tap?

SedanMan April-14th-2003 10:19 PM

The signal wire. Not the two black ones.

Im just going by deduction here.

That guage sucks, it jumps all around like a bug. Team Omni has a great one that uses 4 L.E.D.'s that doesn't jump around it stays off until you get on it then displays the air/fuel with 4 lights.
