    Are there any brake controllers that simply plug into the 4-way flat connector? I'm borrowing a friend's Subaru to tow my pop-up, and he doesn't need a controller permanently installed.

    Make up your own plug and play harness - probably using a $25 wiring kit from walmart. You'll use it again later. Best not to mess with a buddy's stuff who is willing to loan out more than tools!

    Brake controller is usually installed in the front of the tv. I know of none that plug into the 4 prong flat connector, it simply would not work (as far as I know.) There is a plug that you can buy plugs in under the dash and into the back of the controller. ( Unless you are talking about something else)

    I'd build my own harness. Run on keyed power, brake and trigger from front inside car out the back - temp mount with velro to keep correct angle for controller. I'd make up a 7 way female that accepts the stock 4way for light/stop/tail/ground along with my temp 3 wire brake control harness and I'd be running it today. I don't want to draw it out because if you can't catch what needs to be done, you shouldn't be doing it - you should pay somebody to ensure you did it right and safe for you and the borrowed car's power system. Fuses aren't optional either....

    Are the 3 wires for +, ground, and brake?
