Hey all, got a rather strange issue. A bit ago some of you may remember I posted in another thread I was missing my front o2 sensor connector. Well I was gonna leave it til my mechanic could look at it, but I need to be able to run it while it sits and I dont want to kill my new cat already. I dont mean the o2 sensor itself, its there. I Mean the connector it plugs into! Ive searched high and low but cant find the thing anywhere. Its not there. Talking to my buddy who helped me put my high flow cat on, he didnt remember it being attached then either. It confuses me cause if thats the case I should never have passed the e-test I put it through, and shouldnt it run awful without a front o2? Anyways Ive decided to try to chase it down. The wires should be coming from the PCM correct? Does anyone know specifically what wires it is coming out of the PCM? I would assume the wires should be the same color as near the connector?
edit: currently have p0135 and p0132 for codes being thrown.

the truck will run ok with no O2 sensor attached, but it should immediately set a CEL code/light (13x series O2 circuit). the truck will run from its default settings which might be a tad rich, but will run normal.
look for the O2 connectors on top of the transmission. one near the front, one near the rear.
