Hello Ralph. Those connectors are modern 3M scotch “butt” connectors. They are used a lot in trailer wiring and automotive applications. Someone in the past has obviously used them to connect the various wires. You will have to trace them back, to see if there are components actually missing or just to extend the wire. Good job so far. Tony
