As will become clear from this posting, I am completely new to the world of automotive-style wiring. I have laid out my wiring plan (thanks mostly to the excellent store of information and guidance from participants on this website) but now I find myself confused over the simple question of wire connections. Many of my connections will not be accessible without opening walls after the teardrop is finished so I definitely want to get this right. I have read that simple wire nut connections (like home wiring) are not adequate due to loosening from vibration and potential moisture issues. Advice on marine and automotive websites suggests that soldering weakens the wire and soldered joints are subject to breaking with vibration. So I figured I would follow the general advice and use crimp and heat-seal connectors. My question is: what do you do when you need to splice more than 2 wires, as with connections for lights wired in parallel? I have seen 3-wire crimp connectors on line but they appear to be very uncommon. The PosiTap and Posi-Twist connectors (found those on line too) look like they would work, but it seems like there must be a simple solution.
What am I missing??
