O2 Sensor Removal

I have 2004 GC with 4.7 engine (4 sensors) and one of the sensor connectors has been fused together from touching the exhaust with one wire exposed to the elements and giving P0136 code.

1.Can anyone enlighten me on the the best way to remove the 1/2 sensor, from top or bottom? Tool required?
2. Can the male connector (wiring harness) be purchased new or do I have to head to the junkyards?

Re: O2 Sensor Removal

for #1; get some PB Blaster or similar and for about 2-3 days prior give it a spray when its cool on the threads. then get you an O2 socket that has the slot for the wire. and you SHOULD be able to get it out.
