Ok...it's finished. Yikes! What a P.I.T.A.! I decided to put a little penetrant where the male and female plug comes together...waited an hour or so...no change. I decide to try prying the entire plug assembly off the metal arm to which it was held by 2 plastic clips. The 2 plastic clips broke and the entire connection was now within my reach and sight. Pushing the clip down while pulling, now with both hands, didn't do anything. Finally ended up putting a big flathead screwdriver to it in hopes of prying it apart. It stated to separate...but in tiny tiny little increments. I was wondering if someone had super-glued the assembly together! They were finally worked apart, but this thing just did not want to separate. The old sensor came out and the new one went in...then the connection of the "new" male plug was very very tight, so I scraped the interior the female part of the assembly and after working things back and forth a bit, the new plug slid right in and clicked in place. A zip-tie to the metal bracket and the job was done.
This job probably had 15 minutes worth of actual work. Without the trouble with the electrical connector, it would have been a breeze. Anyway..thanks to all who offered up advise. (this was still worth the effort and was lots cheaper than having the dealership do it!!!)
