Stop in for a cup of coffee

Since the car is using an MSD box, to use a single terminal stud for the alternator feed. MSD power will connect there instead of the starter relay.
Both sides of the ammeter wiring will go through a grommet. Same as Chrysler shows in the assembly drawings for 60 amp and leece-neville. Period correct load reduction on the bulkhead connector! :)
just need to find a grommet and some other parts.
