Pigtail for Bulb and socket wiring kit

You cab buy those sockets from Advance for about 4.00 ea. And buy that wire to wire a utility trailer about 7.00. Lot cheaper than Blue ox. Than just get the small, I think 7 pin to mount to the base plate. Than make the short jumper to go from the base plate to MH. My motor home came with a 6 ft jumper, but you can make one up, to fit the socket at base plate and back of MH. And when wiring the sockets, would sorder and use heat shrink, with diaelectric grease in it.
