Have always tried to find a better way to run wiring through the roof with no chance of leaks etc
I have seen many solution for putting the wires through the roof, but wasn't quite comfortable with some or most of them
I wanted to have a total wiring solution that I could easily unplug and remove without having to take everything apart
Here was the key
Its called a DeckSeal
It sits in a anodized housing and the rubber block is about 3/4 inch thick and shaped like the the outer portioned, then tapered at the bottom.
The way it works is you drill the wire size through the rubber , push wire through then when you put the housing over the rubber block it compresses around the wire . This system is used in the high end boating industry
Many different marine dealerships have these but here it is from Defender Marine

It's still running...

Looks like a good idea. Still have to drill a hole in your roof, massive too, lol.
They appear to have different sizes.

We run them on our ambulances. Really good quality and zero leaks. I've personally used them to run wires thru the hull of my boat for the sonar wires.
