Tom,

>From my experience, the exact opposite happens. Without the A2, the motor
will try to lock up when forced to spin in the opposite direction than
indicated by the electrical connection. Hook up the A2 and you get a mild
braking effect instead.

Disconnect the A2 and your truck will not roll very far in reverse. Instead,
once it gains a little speed, it will feel like you slammed the brakes on
(not pleasant). Connecting the A2 will prevent this but it will not stop the
car from rolling backwards on a hill.
