Putting everything back together and can't remember where this phucking thing goes??? Sits behind the coil packs and is attached to the fuel injector / engine sensors harness. Orange colored end and basically sits on trans. Any help?

 

Upstream o2 sensor, don't recall what side gets orange though, hook em backwards and you will know it, engine run like poo

 

Thanks. The other must be must have dropped down and is dangling where I can't see it. I didn't want to get wet by crawling under (raining here).... Lol. Thanks again.

 

There's only one back there tho.

 

There are 2 upstream, 2 plugs, one is orange other is grey or black?

 

there are two plugs for the upstream, they are located on hooks attached to the bellhousing...

I know you did the top end, but i'm curious why you would have disconnected the o2's?

 

Yeah the other one was connected still. I disconnected the orange one cause it was in the way (the bracket). The other end dropped down out of sight. Got it hooked up. Thanks.
