Just thought I would recheck the ignition plug and gave it a wiggle and it low and behold it would cut in and out the gauge sweep, took the tape off and gave the wires a tug and look what I found, not the white wire but the green/black wasn't in the terminal
Looking at all the pic, it appears that connector had already been replaced at some time - the insulators should be all the way inside the shell when assembled correctly.
So it looks like someone had replaced the connector to begin with.
Incidentally the original connector would have been the older type on an '06, so it was definitely replaced at some point (and poorly executed - sorry to say!)
