Before using the relay on the car's brake light, I considered doing it that way. I didn't, only because I had to plug in that connection every time I towed, and unplug it after. I preferred the install once and forget it approach.
(Actually, when I installed the relay, I went into the trunk of the car and spliced into the wire that feeds that trailer connector. One of the brake light/turn signal wires and ground. Since the car's turn signal will never be on while towing, it works perfectly.)
As far as modifying the 7 pin, I didn't want to make permanent changes to the MH. Everything I have done can be removed and leave the car and MH as originally wired.
