I had done it the same way, but after about 6 months, it started to not work while the truck was on. It would flicker on and immediately turn off... After that I just installed a an aftermarket with the flexbed connector. Only con for that is I can only use the bed lights while the truck is on...
Hey MTC,
Ordered my Bakflip MX4 a couple of weeks ago and the rails came in a little bent and one of the rails' rubber was peeling off a bit. I'm sure these could be glued back on and the rails bent back straight, but I called up Bak and got replacement rails since they were damaged in transit...
