Parts needed for 12v conversion:
1. Resistor for fuel gauge (+) terminal.
2. Ballast resistor between ignition and coil.
3. 12v coil.
4. 12v alternator/generator.
5. 12v bulbs/fuses.
6. 12v headlamps
You may also want to get a 12v heater switch and blower motor, as the variable resistor will likely melt even with a voltage reducer on the circuit.
