Tech tips 6
When connecting 2 wires together, don’t take the cheap shortcut with electrical tape or wire nuts. Trailers vibrate, flex, bounce, get wet, get hot, get cold, and generally try to destroy anything installed on them.
A poor connection today becomes a troubleshooting nightmare later.
I recommend soldering connections whenever possible. One of my preferred options is using solder seal wire connectors. They give you a much more solid and reliable connection while also helping seal out moisture and corrosion.
Clean wiring matters.
Reliable connections matter more.
