Hi guys, I'm having problems when connecting to a trailer, i have no brakes/indicators.. I've changed the 7.5 fuse on the passenger dashboard as my front sidelights and rear left light was out and that sorted it but still no joy on the rear electrics, any thoughts? Thanks

have you tried a multimeter in the socket to check ther is power there? If there isn't look under the rear of the truck , trace wires back , should be a join where the trailer sockets join the main loom
