MSD Launch Control

PN 8735

IMPORTANT: Read these instructions completely before attempting the installation.

Parts Included:

1 - Launch Control

4 - Mounting Screws

WARNING: During installation, disconnect the battery cables. When disconnecting the battery,

always remove the Negative cable first and install it last.

The MSD Launch Control allows you to select

three different rpm limits. Two limits, the race

and burnout, are adjusted with plug-in modules.

The launch (or holeshot) limit is adjusted with

the two rotary switches (Figure 1).

The launch and burnout limits are activated when

12 volts are supplied to their corresponding

activation wires. When neither limit is activated,

the overrev limit is active.

It is recommended to mount the Launch

Control within easy reach of the driver so last

minute adjustments can be made to the launch

rpm setting. Also, make sure the wiring reaches

the MSD Ignition. Mark the location of the mounting holes, then drill the holes using an 1/8” bit. Use

the supplied mounting screws to secure the Control.

This connector plugs into the rpm module socket of an MSD Ignition or Rev

Control.

Note: The Control will only operate when this is installed one way. It is

correct when the LED on the Control lights when the ignition is turned On. If the

LED does not come on, turn the 2-Pin connector around and try again.
