Well there was no continuity from pin 28 to common pin 31 so I took the plug apart and I have some good news and some bad news. The good news is the plug looked brand new when I opened it and all the wiring was good, the bad news is the wiring was good.
I am not sure if I will take the TMU apart yet as I want to enjoy what I have at least for a while before I take it out of commission, If/When I take it apart I will update this thread or I just might buy a different one I am not sure what direction I will go yet.
Thanks for all your help
Brad
