When all else fails, consult your handy rule book:
21. REV-LIMITERS: All competitors must compete with a
rev-limiter that is correctly hooked up and in use at all times.
No quick disconnects may be used when hooking up the rev limiter.
The rev-limiter must be wired into the toggle switches
as delivered by 600 Racing, Inc.. The rev limiter must remain
stock (maximum 5,600 rpm) as currently provided by 600
Racing, Inc. No modifications are permitted to the rev-limiter.
If the rev-limiter does not work due to improper wiring or
bad connections, the driver will be disqualifi ed.
