My friend bought a 1998 V70, the catalytic converter had been stolen out of it before and in the process a bunch of wires got pulled loose.

The only thing he needs to do still is reconnect the O2 sensor to the wiring harness. The issue is the cap that plugs in to the wiring harness was pulled loose so he has to reattach it to the wires. There are four wires that go into the cap: green/white, green/black, green/orange and brown. Can someone out there help us with figuring out what order those wires should be in?

 

Did you figure it out yet?

 

Hi, I'm the friend (owner of the car). And no, I haven't figured it out yet... I tried to ask some of the local mechanics around town, but the best response that I've gotten is they'll look at it, and it'll be atleast $80 for them to fix it... Which I don't really want to spend... I just need to know which wire goes where... basically, at one point, before I purchased the car, the catalytic converter had been stolen from it, and the person that did that just kinda yanked the wires out when they were doing it. This ended up causing the cap that would normally be on the wiring harness going to the O2 sensor to be ripped off, and now I have those 4 wires hanging loose. Everything on the O2 sensor side is normal, and i was planning basically to connect those loose wires into the o2 sensor cap, so that it will make a firm connection, so that I can pass inspection with this vehicle. It's a pain.

 

Also, the craziest thing about it is that the o2 sensor cap, the wires that run to it are White, White, Gray, Black. I have no idea how they match up.

 

I will see if I can dig up some pictures that might help the best.
