I was trying to hook up my air/fuel gauge.And i think i hooked it up wrong. I hooked the air/fuel gauge wire into the black wire on the O2 sensor.Well i couldnt get to the front one so i decided to use the back one and now its not reading anything.Did i hook it up wrong..HELP thanks

 

I'm no expert on this, but I hooked up my a.f gauge to the front d/s O2 sensor and mine works fine. A little jumpy but a light show never hurt anyone.

I used a Pigtail Harness from South Florida Pulley Headquarters. Worked like a charm.

I dont think ill have any problems with it after i hook it up to the front o2 sensor..
