O/D Wiring harness connection

[EDENMA@aol.com]

Hi listers!
 
I have a late model single rail O/D gearbox I am trying to install into my  
wife's 73 Spitfire. Along with the new gearbox, John Esposito supplied  a 
transmission wiring harness but I have no references in my library of  manuals 
which show what each of the switches on the gearbox are or which color  coded 
wire 
goes to which switch.  Can anyone help point me in the  right direction?
 
Thanks,
 
Mark
