I have an MSD ready to run billet distributer. My vehicle is a 65 Chevelle with a 327, 350 trans. I have done some research here but still have a few questions on wiring this distributer. There are 3 wires on the distributor , black, red, and orange. The black one goes to the ground, red goes to the positive side of the coil, and the orange to the negative side . My question is, What wire do I use to hook up to the positive side that goes to the ignition switch ?? I have read here that I cannot use the cloth covered wire that comes from the fuse box( I have the original fuse box). I have also read that I can use a whole separate wire from the IGN spade terminal on the fuse box to the coil. If so , what gauge should I use ? My fuse box has 2 spade terminals labeled IGN. I am already using one for my electric choke. Is it ok if I use the second one for the distributor. ??? Thanks in advance.

Use a number 12 guage stranded wire from the IGN connection (switched 12 Volts) to the coil plus connection and on to the MSD. You don't want to use the stock fabric covered wire because it drops the voltage to 9 Volts and the MSD won't like that. It's fairly simple. Just make sure to get a full 12 Volts to the MSD.
