Hey guys, I'm installing AF gauges in my car, and I need to know where I need to get the signal for the sensor. Can I tap directly into the 02 sensor, or do I have to go to the wiring harness of the car? Thanks! -Mike

 

DO NOT TAP THE O2 WIRE!!! You wont get an accurate reading if you do. You need to take it from the computer, im not sure which wire. Ask around; I'm sure somebody has the answer.

 

Thanks! Now, Which wire?! Should I run the wires through the engine bay to by the PCM? Thanks guys

 

Try going here http://autometer.com/hp/ click on insructions then click on AF gauges, but you have to have adobe reader. Hope it helps.

 

Thanks!

 

I've looked around on that site, and I can't find the right wire. Any suggestions?

 

first off the gauge isn't all that acurate to begin with and secondly the 02 is the same signal as at the pcm. just tap into the purple wire and the purple wire with a stripe on the 02's.
