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.
