Hi Guys, I hope this makes sense.

I want to be able to have all my additional equipment on a separate circuit, which I would have to energize with a pulse (i.e. old horn push type button) then when I release the parking brake all would switch off until I re engage the parking brake and press the horn type button again.

Can anyone help, many thanks Nix
