Thank you Eric,
Let me try this....I had tried this before contacting you, but could not get it to release. Will try again.
There are 3 connectors. I have released the one with the single wire which was released with a tab on the side.
There are two stacked on top of each other, a green one, and I believe a black one. Like you say tight, and don't see a release tab even with the mirror.
Have released all of the 5 connectors. After getting that green one out, then it became easier to see and to get my hands in.
Took more sweat, and stronger fingers...but you had it right. Not much more you could do for me except to say...work at it!
