RV towed vehicle project: installing tail lights. 

I ran my wiring thru the engine compartment and then dropped down and ran along frame rail using wire ties already in place for factory wiring running to rear. 10 minutes tops. Used a body rubber plug to get into the trunk. No use to fret going thru the passenger compartment. Great video. thanks for your effort in posting.

:Ugly or not ugly" that's a good question ;)....I think thats waaaay last thing the cosmetic part of it as long it will be safe and functional. That is how I look at it. You do nice detailed job all it counts> I am next

Brilliant.
