A type overdrive wiring

[TR6me@cs.com]

I recently added an a type overdrive to my 72 tr6. I purchased it from an 
auto wrecking company and was expecting  all the switches on the top gear 
selector to be correct. that was not the case. It came with one switch on the 
drivers side and one on the top. I was told this is not correct. If someone 
out there has an overdrive that is original and could help me with the proper 
location of these switches and the wires that go to them it would be of great 
help to me.
