And it works very well... AND 407's have all the sensors built in, all you have to do is hook up the rads to the left of the front pannel.
407's don't have the sensors built in. The wiring for the mag pick-up is built in, the rest must be installed for each track and balance.
RADS is the only thing approved by Bell for the 407. Remember, just press DO!
