i asked the same question about my 2000 r/t in the troubleshoot forum. no response yet. im still lookin if i find out tho ill let u know. hey, are the color of ur wires, one grey, one black, and two white?
Black wire = signal
gray wire = ground
2 white wires = sensor heater
You need to hook into the black wire and it will work fine. I got mine hooked up and works great. I used the frist O2 sensor on the driver side. The gauge looks cool to. Looks the light on the night rider car. :mullet: If you have any other question just ask me.
thanx, i jsut found that out too recently, i also found out u can tap in on the pcm harness aswell. i might do that since i wont have to run as much wire. but i know the meter bounces back and forth and ive been waitin to watch it for weeks now and now i know how to hook it up.
