Re: ACC or IGN?
When I built my 67 Malibu, I effectively added a second electrical system to support all the stuff I added - Accuair compressors, Holley ECU, electric fuel pump, MSD 6AL box, etc. While the 50 year old wiring was in good shape, it couldn't handle all the electrical demand (i.e., amps) I was adding. I only tapped into the existing electrical for signaling to the relays - not to supply power to any of the devices. The junction box from Painless is a great way to accomplish this. I also relocated the battery to the trunk which actually made it convenient and nearby to locate the distribution, relay and other components.
