all these are good, and "must do", I would add that you should put a dab of dielectric grease on the all the connectors and to use only clear RTV silicone, I am willing to swear the black and red have made me loose hair on some **** built Electrics in an ice cream plant in Miami. Make sure all the "heaters" work, and let them run when the truck is out of the freezer for less than 15 min even in high outside temps, it will hasten the drying or preventing of sweat on the switch areas.
