For what it's worth, I also have a Prodigy (I believe mine is a P2) and was not able to lock the TM brakes with it installed in my Sienna and still can't with it in my Tacoma.

When manually activating the Prodiigy lever, I definetly feel the TM brakes, but not enough to come anywhere near locking them. I've never felt like the TV is being pushed by the TM, but don't have a reference point to compare to to know if I'm trully getting maximum power to the brakes from the Prodigy.

The only time I have felt it lock the brakes is when I made a tight turn and the break-away cable wasn't routed properly and the plunger came out of the emergency brake activator.
