[TR] TR2/3 control head information

[Angelo Graham]

Hello List:
Just about to embark on installing a new wiring harness on my TR2 
control head. I do recall the big mess I had on my hands when trying to 
"rebuild" the control head on an earlier TR3 project.
Has anyone come across any detailed photos/instructions on a control 
head rebuild & re-wiring? Want to be a bit more prepared this time around.
Thanks for any help anyone can provide.
