Bob,
Thanks again, your right about needing the part numbers for GM parts
direct - I was getting no where real fast using the limited information I
had, needless to say this info will be tucked away in my newly created EFI
file.
I believe your also correct about Tracy system of  solder to the pins
looking attractive - you know I would never have thought of that, but
learning every day. Of course I'd prefer the plug if one were available and
it most likely is, given the availability of everything else - it's just
finding it!

I'm still in the process of sorting everything out and I have to admit to
leaving everything to the last minute, as I have very limited knowledge in
this area.
