Are these the correct Packard connectors for the bulkhead connector?
Variously termed "Packard 56", "56 Terminal", also w/ "GM/Chrysler". BTW, Packard refers to an electrical manufacturer not the automobile model. They interchange w/ common 1/4" "spade terminals" in any auto parts store, though most don't have the latches and newer male type have a side latch. Also used in relay bases and home appliances. Gold-plated are best. People constantly argue whether soldering after crimping helps. I do, since at least the soldering provides some corrosion resistance.
