A very long time ago I made my first 4 wheeled vehicle from
two wrecked Peugeot 404s. When I put the dashboard in I used
barrel splices, probably similar to your butt splices. After
crimping them I soldered them. The solder wicks in just like
a sweated pipe joint. I don't recall what I wrapped them
with - probably rubber tape. I then put more than 100,000
miles on the vehicle with no electrical problems. (Upstate
NY)
