So I am going to be installing an MSD ignition and FAST EZ EFI. Both of the instructions call for wiring directly the battery + and -. I don't like the look of extra wires hooked up to the battery posts as I think they look tacky. I was thinking about getting a negative cable with the extra pigtail built in and connect both - wires to it. As for the positive wires, cutting the aux wire that goes to the starter relay and tying in close to the battery. Anyone else have better ideas on this? Car is 68 charger with 440.
