Reminds me to do the bed light checking. One has been intermittently working for a couple of months now until it stopped working last month. We'll just finish first the installation of the brake kit, lexani rims and head ache rack on brother's truck. I suspect it got bad connections through the bolts since it got wet a couple of times and probably rusted. I like the idea of putting a jumper on both ground terminals to ensure the connectivity in case one of the bolts is not having a good connection. As for cleaning the possible molds, I will try using the sand paper first. Been doing the sand paper cleaning most of the ports of connection as it cleans the surface thoroughly.
