1952 Saratoga need help

electronics in 52? IIRC the electric contact is probably an overdrive cut out. Does the car have an overdrive trans? If thats the case, it may be done with a hobbs pressure switch or a microswitch on the carb, eg. like a nitrous switch setup.

here is some info..."The electric control system works off 2 wires connected to the coil. There are 2 switches built into the carburetor to control full throttle and closed throttle shifts. The wiring goes to the transmission which has a governor, a solenoid and a switch."...Good luck.
