I knwo I have to tap into the black wire but it would help if I could even find where the O2 wires are even located.

 

under the truck right behind the driver's side wheel, locate the O2 sensor sticking out of your exhaust pipe, tap into black wire.

Dats it.

 

Speaking of O2 sensors, ever since they replaced the passanger side head on mine its had a rough idle. So just out of plain curiosity, I hooked a scan tool up to my friends Lightning and compared it to mine. Every thing checked out ok except my O2 sensor voltage!(bank 1 & 2) His graph was consistant with perfect up and down lines(if ya know what Im talking about) but my graph was all over the place, nothing consistant at all! The lines would start up or down then start breaking apart. Anybody with more knowledge have an idea whats going on? Im still green on the scan tool operation and readings.
