Putting '94 Cummins 12v with 47RH tranny in '62 caddy. Using manual valve body and shifter from Muldoons to handle shifting. I have tried to find a wiring diagram to determine how to get power to the shifter but can not find one. Will "any" power work or is there something more I will need? I do have the shifter connected to the transmission, just wondering about power source? Thanks for the help!
