I am in the middle of rewiring my 55 wagon and have now gotten to the transmission. I have a couple of problems now. First, all my original wires were torn out before I got the car so I have to start from scratch, this is Ok everywhere else but a bit overwhelming at the transmission. Second major issue is that I am now have 12 volts instead of six.

Does anyone have a simple diagram for wiring up my trans. I don't need that fancy of wirng just enough to get the overdrive working safely for a few months until I swap in an AOD trans. I have a schematic for the car but I have heard that some of the wiring could possibly be eliminated to simplify the circuit? 

Thanks
