You could do it that way, or install a small fuse block and run a heavy lead up to it and power all your accessories on separate circuits from the fuseblock. I used the individual inline fuses for my heater and another for the directionals. The headlight switch (if if original) has a built in circuit breaker so no need to do anything with that circuit unless you're adding a "lot" of lights or a mega sound system. If you're going to keep it 6v to change from + to - ground you're going to have to repolarize (can't remember which) the generator or voltage regulator, switch your batt cables, and if you keep the ammeter switch the lead on that or it will read in reverse. If you leave it 6 you're also going to have to switch the coil leads (I think). I did a straight 6-12V conversion using an internally regulated Delco alternator. I switched the bulbs, put a ballast resistor in the circuit for the fan motor, swapped to a 12V coil. My gas guage doesn't work-but down the road when that is fixed that will need a resistor installed in the circuit before its hooked back up. Mike
