1990 oxygen sensor location

I have a dilemma with my 1990 4.9. The PO had taken out the oxyen sensor before and now I have a new one to install. The problem is that I can not seem to locate where it plugs into?!? I have looked every where and there is a few open plugs from the AC being deleted but thats it.
I was wonderiif anybody has a picture so I can see where the wire come from for the sensor. I am guessing the plug was ripped off at some point.

Thanks

Ranger,

I am a Product Specialist with Walker Products, a worldwide distributor of auto parts. Here is an illustration of the O2 sensor (HEGO sensor) plug on a 1990 4.9 F-150. I hope this helps.
