I'm sorry if my comment came off as harsh, it's just that kind of stuff- now that parts are getting harder to get and more expensive- I just cannot let it slide. It ultimately costs you money when/if it fails. Twisted wire connections under what might be a form of clear electrical insulating goop?
I understand wanting to add cab lights and being creative is not a bad thing. But, execution here- a lot of bare wire exposed, possible short to heatsink sharp edge metal- and knowing what the damage could be, and what it could cost you, IMO isn't worth the risk.
I'm not saying every job I ever did was perfect, but long, long, long ago, I learned to solder and use heatshrink because twisted wires and bad insulating jobs just tend to cause more problems than they ever solve.
Don't use that same method of wiring and splicing on the 3rd rail power pickup.
