Continuing with the theme of well-organized and properly fused wiring, I wired my LED lights through a Blue Sea distribution block housed inside an IP rated enclosure in the engine bay. The control wiring is run via a multi-conductor machine control cable through a gland in the firewall. All switching is done with water-resistant relays, and the main power rail is protected with a circuit breaker near the battery.
Again, if you’re going to run large-gauge hot rails it’s really worth protecting them properly. Fires are less than ideal.
