I even went the extra 10 miles and smeared 3m 3500 under all the heat shrink tubing before I shrunk it. Did I mention how sick I was of having to work on trailer lights before every $%#( trip!?

Of note: I once had a short on this trailer that took out the fuse for my running lights on my RV. At the same moment, the short destroyed my anti-lock brake CPU and I suspect it initiated the slow death roll (gradually increasing heat sensitivity/failure) of my Engine Management Computer in the same RV. $300 worth of electronics and about 30 hours of my time and I have a new anti-lock brake unit (ebay!), EMC(Autozone $$), and an ISOLATED trailer lighting system on it's own fuse. Now we're ready to roll!
