FiTech EFI system

Yes, they are just sold by size. Many Accel pn's are in the process of going discontinued after the msd acquisition....which was followed immediately by the holley acquisition. But I can see if they have any left. I think they were more money though.
FYI this is the wiring diagram that I followed for the timing control setup. Currently the coil neg is connected to the black wire on the fitech unit and then the distributor is plugged into the Fitech (green/purple) plug. The only thing connecting the coil to distributor is the main wire.
