Kwikee Doorstep

Thanks all. My unit has the red box controller. A dog chewed the wires on mine. After rewiring it, some time it works and some times not. It worked right before the wires were chewed into. The dog chewed a ground strap that was 1 inch wide. It also chewed all the wires off a trailer, mud flaps and other hoses and plastic tubing. Stopped the dog from chewing by attacking a fence shocker to the trailer for a couple of days.
