Thanks for the suggestion BillsGU. I wired up my spotlights, tail lights and Reverse spottie (also replaced gearbox switch), the cabin light and replaced and soldered all the wiring in the ARB bullbar (park/indicators) when I went to LED- and the horn wiring and unit. I respect that a sparky would be conversant with this, but as a qualified Fitter/Boilermaker I like to do what I can myself.
