O2 Sensor connector location?

[zwack88]

Ok awhile back I swapped out my manifolds for headers and a offroad h-pipe. Ok did that and I obviously needed longer wires on the o2 sensors. Scott said get some out of a Mark VII so I got the ones with the longer ones for like a 89 mark VII. Got them in and now I dont know if they are long enough or what but I cant even seem to located teh connectors in the engine bay. I remember when I disconnected them that they unplugged from the back of the upper intake. I feel around back there and nothing unless i just keep missing them.

So yeah I have drove this thing like a 100 miles if that without o2s hooked up cause I was lazy, service light never comes on until maybe 20 minutes of driving. Anyway I am going to take her out of the garage and drive her back next week so I can put some miles on her so I want my o2s hooked up and working.

Thanks.

There up there, man. Gotta fish for 'em. They could be hooked up on that firewall padding.

Btw, CarQuest part number for those O2 sensors is #75-1517. Don't know if that will help anything.

The main connector plug for the harness is right near the vacuum tree, the connectors for each O2 sensor will usually be laying somewhere behind the lower manifold on the back of the block. Have to dig around with a light to find the things.

Alrighty I got them plugged in. The connectors slipped down to atop of the tranny hump. Thanks guys!
