Caravan - Convert Old 12v Socket to Modern USB

Our Swift Capri caravan had the old fashioned 12v sockets fitted using the Clipsal fittings. I bought a Clipsal blanking plate and used it to house usb sockets. Then swapped it out with the caravans original 12v/Aerial socket. We now have plenty of USB charging points in the caravan, far more useful than an old 12v system nobody uses anymore ! Bit out of practice doing these kind of videos, not done one for years, bear with me lol.
