Where does this wire go

[Rokhound]

Ok guy here is the thing I just replaced the head on my 92 XJ 4.0 HO the people that I bought it off of start to do some of the work. So I am trying to put this darn thing back together and I have must of it done there is just one wire that I can’t figure out were it goes so I hope some one can help me. On the front of motor next to the fuel rail there is wires that run through that piece of plastic and at the front of the motor there is one that goes to the water neck and then this really long one that I can't for the life of me figure out where it goes. I no pic would help with this but the wife is a sleep and I don’t know where the camera is so as soon as she get up I well post pic of this wire. Also I seem to have a leak around the manifold can so one give me a tip on sealing this up.

 

Thanks

Sounds like the O2 sensor, it should have 4 wires
