I was a deisel mechanic for several years. Truckers liked to add fancy chrome lights to their rigs. They figure the easiest way to tap into a harness is with scotch-locks. That truck drives through the elements and the scotch-locks become the vessel for corrosion. I hated tracing an electrical problem to find a clump of electrical tape with a scotch-lock that has turned into ball of green corrosion. Weatherpack connectors are best for the elements, but if you have to do wiring work on something exposed to the elements, at the very least use heat shrink butt splices. That's why I hate them. Yeah, most arcade cabs aren't exposed to the elements, but there's a better way than using those ---smurfing--- scotch-locks. They look like ---steaming pile of meadow muffin--- too.
