After I asked I read Daniel's post about the third brake light hack job and saw yours. Your mention of scotchloks conjured up this image for me.These butt connectors are same as approved by FAA for repair of Airliners. They are not autostore parts. I have a special crimping tool that goes with them. I get them at Terminal Supply. The outer sleave is shrink tubing with a hot melt glue that glues to the wire sheath making a robust connection.
Solder on the other hand is a big no no on automotive wiring. The solder is solid and where this solid solder stops creates a stress concentration in the wire and can and does lead to internal failure of the copper. Shrink tubing that does not bond to the wiring sheath does help a bit but why take the risk... When I started managing offroad racing The Ford racetrucks failure rate was about 75% and most electrical. We instituted a requirement to switch to the type of butt connectors sold by ReyChem or Terminal supply...It is now very uncommon for the race teams to have electrical failures due to wiring.
