MSD-8737 - MSD Ignition 3-Step Module Selector for Use with MSD Soft Touch Rev Control Systems

The MSD-8737 3-Step module selector is designed to work with MSD ignition boxes that are setup with soft touch rev control systems. The box comes prewired with a connector to fit the soft touch rev control port on the MSD ignition box plus a two 12-volt input signal wires and ground. The box contains three rpm module ports and is normally used to allow one port for burn-out rpm control, a second port for launch rpm control and the third port for high rpm control. No rpm modules are supplied with the MSD-8737 box, they must be purchased separately.
