I did both the one front landing gear and the rear stabilizer switches. Bought Menards while at Goshen. These are spring loaded covers are aluminum and seal better than stock Cooper outlet covers. Required from cutting of original switch Bezel and held into the flip cover with hot melt glue. Siliconed sealed the flange to the trailer. One other reason is I can lock these to prevent kids in the neighbourhood from messing with landing gear or jacks.
