02 WJ V8. The connection for my rear oxygen sensor fell and got melted on the exhaust. It buggered the plastic connector that connects the oxygen senor to the rest of the system. My problem is I can't figure out which wires go where. The sensor has a black, a gray and 2 white wires. Where they connect to has violet/orange, red/white, black/gray and black wires. I've even got the factory wire diagram for the entire vehicle and I can't figure this out. Someone happen to just know or maybe want to crawl under theirs and look? I'd be forever grateful!
