Negative Switch Brake Wiring & Electric Brake Controller Help
I'm attempting to add an electric brake controller onto my 05 Monaco Knight. Thought I had it 'made in the shade' when I found the 4-wire pre-wired wiring harness under the dash marked "Ignition, Ground, Brake & Trailer Brake". But noooooooooo...when I tested the plug what did I find? The Brake lead was hot prior to pressing the brake and cold when the brake was depressed. So I began to research the US Gear website (Monaco tech support had told me the RV was pre-wired for US Gear controller). I saw a comment that stated "some late model Roadmaster chassisís use a "negative" switched air switch".
Does anyone have experience with this type of setup? Is there an alternative site where I could connect to the brake?
I've got an email into Monaco Tech Support, but thought I'd try here as well.
