    Hi Folks, I found a plug hanging under the truck I just bought. It was hanging next to the tranny near the front driveshaft. It has the factory "RR" tag on the wires. For the life of me I can't find where this thing plugs in! The check engine light is on and I suspect this may have something to do with it. Does anyone have a wiring diagram they can look at and tell me where this thing plugs in? Thanks.ussmileyflag

    It's a 2000 Ram 1500 SB Reg cab with Off Road pkg and 5 speed manual tranny.

    Post up a pic. I swapped a 5 speed into an auto tranny truck and have some pictures of all the wiring. Plus I still have a 99 V10 so the wiring should be similar.

    You hit it right on the head. When the previous owner put a cat back system on the truck, they eliminated one of the oxygen sensors. I'll weld a bung onto the pipe and install a new sensor this weekend. Thumbs Up
