hooking up air/fuel gauge

i got a 3 wire a/f gauge from autometer and it was actually pretty easy to hook up. the three wire colors were black, red and purple. obviously, the black goes to ground and the red to power, so the off color should be the o2 signal from the sensor...this is for a 3 wire a/f gauge so i'm not sure otherwise...

You should tap off of the ECU harness instead. Simply for the reason that the connection wont be exposed to the elements as if it were tapped off of the O2 sensor.

The four wires on your O2 sensor are identified in your service manual. If you dont have a manual, email me and I'll look it up for you.

its the fat white wire.

yeah i got the autometer 3 wire one, so the purple wire goes to a fat white wire... ill take a look in the morning....

thanks

bb6 h22a, what service manual do u have cuase i looked in mine and i didnt find one.. i really need to get a helms manual...

i would recommend splicing into the wire at your ecu. you can get the ecu diagram from apexi's website (i dont know the link off hand and its late) its not difficult.

peace
