Its a snap gone need suggestions

You can rewire it yourself. That way you can customize as needed, for electronic ignition, AC, fan, etc. I did that on my 65 and 64 A's, using a relay box from a 90's Jeep. You can buy new "56 terminals" on ebay to put in your bulkhead connector shells. Your 65 bulkhead connector is unique in that the cabin side has big "buss-bar" feed-thrus for the high ammeter current. Indeed, I like that design so much I got one to put in my 64.
