Ths to Harvestr, Doug, Bruce, Alan, et al for the help.
I would suggest the following additions to the installation instructions:
1 There are 2 plugs. Attack the inner plug first. Attacking the outer is futile (I have proof)
2 After pulling out the inner plug use the 'tool' to pull the outer plug out (from the inside) to give yourself more manevuring room.
3 The "tool" I used is an allen wrench attached to the end of a Vice Grip - works GREAT - for pulling the 'thingy' back into place. Need a long allen wrench and / or a needle nosed Vice Grip for length.
