ignition system. However, the only accessory included is an RPM activated switch. This

RPM switch is controlled by two rotary DIP switches that are located behind an access plate

on the top of the unit (see the illustration below). Loosen the two screws to gain access to

the switches.

You can select 4 or 6 cylinder operation, and an RPM switch value from 1000 to 9900 RPM.

Use a small screwdriver or similar to select 4 or 6 cylinder mode, if desired. If both these

switches are off, the unit is in 8 cylinder mode. Use a screwdriver to set the 1000 RPM and

out of the end panel will be connected to ground (10 amp maximum).
