Actually, I forget, are you controlling fuel at the same time your are upgrading spark control? I recommend picking either fuel or spark to control first and then move to the other one once you are comfortable with the one you have started on. Makes it so you only have to troubleshoot half the system if problems arise, being as it's your first one.
If you just start with fuel control, and leave timing control alone, aka mechanical and vacuum, 4-pin module, for a while, then just connect Pin#24 to the TACH port on the HEI cap and call it done until you go to upgrade for spark control. Then follow everything I've been saying in previous posts for spark control. If you are leaving the carb in place for a while, then do spark control first.
