68 Baracuda electrical questions

In 1966, they added a 3rd bulkhead connector, which is termed "wiper connector" since most of those new wire positions were due to moving the wiper motor into the engine bay. I have run across 1980-90 Dodge vans in the junkyard which still used many of the 1960's connectors, including the bulkhead I recall, but sometimes with 4 connectors. I don't know if keyed similar. Indeed, I vaguely recall the latches on the plastic connectors changing from male to female or such over time, so not all interchange, but I have found some matching connectors for my early-A's in later motorhomes. The metal terminals are termed "Packard 56" or "56 terminal", also used in GM. Many sellers for those on the web and ebay. The plastic housings are harder to source though a few new ones are made. BTW, don't fret if the plastic bulkhead latches break off. The connector will stay on, indeed wiggling them off is usually hard. Use silicone grease on the terminals.
