1.
Attach the BLACK wire to a good engine ground. Make sure to remove
any dirt or paint beforehand.
2. Attach the RED wire to a 12 volt power source controlled by the ignition
switch.
3. Attach the YELLOW wire to the coil’s negative terminal.
4. The ORANGE wire is not used for Non-HEI type systems. Use the provided
end splice to isolate this wire.
5. The WHITE wire is a tachometer output, compatible with most modern
tachometers.
HEI type systems. (FIGURE 2)
1.
Attach the BLACK wire to a good engine ground. Make sure to remove any
dirt or paint before hand.
2. Attach the RED wire to a 12 volt power source controlled by the ignition
switch. On GM HEI applications remove the original ignition switch wire
from the terminal marked “BAT” on the coil cover. Plug the provided adapter
harness onto this terminal and then reconnect the original ignition switch
wire. Attach the RED wire to the open position on the adapter harness
3. Attach the ORANGE wire to the coil’s negative terminal. On GM HEI
applications plug the ORANGE wire onto the terminal marked “TACH” on
the coil cover. If the terminal is currently used, remove the wire, plug the
provided adapter harness onto the terminal and then reconnect the wire.
Attach the ORANGE wire to the open position on the adapter harness.
4. The YELLOW wire is not used for HEI type systems. Use the provided
end splice to isolate this wire.
5. The WHITE wire is a tachometer output, compatible with most modern
tachometers.
SETTING DIGITAL REV LIMITER
All settings can be done externally through the rotary switches on the front of
the rev limiter. A white dot on the rotary portion of the switch indicates the
switch position. Use a small flat blade screw driver to make adjustments.
1.
Rotate the cylinder selection switch to the proper cylinder number for your
application. The white dot on the face of the switch should point to the
appropriate cylinder number. A slight indentation should be felt as the
switch is turned. This signifies proper switch alignment. Note: The Digital
Rev Limiter will only operate in 4, 6 and 8 cylinder modes.
2. The Digital Rev Limiter is not designed to be used as a governor. If the limit
is set too low, and engine RPM is allowed to push up against the rev limit,
failure to the Digital Rev Limiter or engine may result. Choose a desired rev
limit. The Digital Rev Limiter has a 100 RPM
resolution. This means that the rev limit can be
set between 100 and 9900 in increments of 100
RPM. A typical limit would be 5500 RPM. In this
case the 1000 switch is set to 5, and the 100
switch set to 5. By turning both switches to 0,
the rev limiter is rendered non-operational.
