Electrical Bulkhead Connector?
The early A's are simpler and varied more. They have 2 connectors, not the 3 when they moved the wiper motor to the engine bay (1966?). 1965 is best since it has dedicated lugs for the large ALT and BAT wires, instead of running them thru regular 56 terminals as in all other years except 1963. Those big wires tend to melt the plastic as they age and corrode, sometimes even dropping down to touch something they shouldn't (like IGN). I put a 65 bulkhead in my 64 to get that. 1963 had one regular connector and one half-width.
