upstream 02 rewire
 

Hey guys my wiring harness on my 00 Jeep Cherokee for some reason was hanging down by the front Drive shaft and well got caught up in it and ripped the wires right out of the plug. Vehicle side pin #1 is solid green pin #2 is solid black pin #3 is brown yellow pin #4 is black with green strip sensor side i have one gray a black and two whites.

So basically buy a new 02 sensor ???????????

I just had the same thing happen to the downstream one. I actually bought a replacement sensor and didn't see the wire problem until I went to change it.

It's safe to splice in new wire if you're broke or the sensor is fairly new, but I'd just replace the whole thing.

Missed one Cruiser.
