Default Re: Towing H3 behind motorhome?

Oh my friends
H3 has electric assist brakes. What I did was relay power to the assist system while also disconnecting power from the H3 power assist and changing to the RV, while also charging the H3 battery . I did this so I would not drain the H3 battery and not leave the key on. I just plug in my towing cord all this happens, its simple wiring and relay. Brake Buddy works fine if you have power assist working which it is. I amazed the folks at Brake Buddy. If anyone is interested PM me and I will send the drawing to show you how.
