Well, I just got it off using a long narrow wood chisel. Had to twist the connector and, using the string to keep tension, slide it under the connector and twist it off. Then the real fun began, that left the ECM side with about one half inch of free movement and no ability to see at all once one hand/arm was in the small space, so fitting the connector seemed impossible. My wife offered to help and that was the only thing that made it possible. She could see her hand and the connector and with me under the truck and her guiding me to the under side of the not visible clip till I got a tenuous grip with three fingers and she managed to push the connector on... I could barely believe it when I heard the click. Up and running perfectly.

 

I just wanted to say publicly, thanks to all that chimed in. Though it is raining here, has been for a couple of days, and will for a couple more, i feel a lot better now knowing the actual location. The video was spot on. Now it looks as if I need to get an d/s exht man gasket & flange gasket to complete the install.

Just another reason that I joined!!! Have a great week all!
