CYLINDER SELECT
The Soft Touch Rev Control comes from MSD
programmed for 8-cylinder applications. It can
easily be adjusted for operation on other en-
gines by cutting the cylinder select wire loops
(Figure 1). If the loops are cut, use the supplied
insulating caps to seal the wire ends.
MOUNTING
The Rev Control can be mounted in the engine
compartment but away from direct heat sources. It is recom-
mended to mount it where the rpm module is easy to access
for rpm adjustments. Make sure all of the wiring reaches their
connections. Once a suitable mounting location is determined
mark the location of the mounting holes by using the unit as a
template. Remove the unit and use an 1/8” bit to drill the holes.
Install the supplied mounts and use the four self tapping screws
to secure the Control (Figure 2).
