Does anyone use this brake controller on their TM? It mounts on the trailer rather than in the tow vehicle. I'm not considering getting one, but I know someone considering getting one for their 2720 if they get it. There appears to be a junction box about 5 or 6 feet from the from of the TM that the Bargman connector cable enters. I'm guessing that's where the Autowbrake wiring would connect to the electric brake wiring.
