Summary of Contents for MSD Ignition DIS-2
- Page 1 MSD Digital DIS-4 Multi Channel Ignition PN 6215 The MSD Digital DIS-2 Dual Channel Ignition can be used on 4-cylinder engines equipped with two dual output coils. The MSD Digital DIS-4 Multi Channel Ignition can be used on 4, 6 or 8-cylinder engines equipped with up to four dual output coils.

Page 2: Theory Of Operation
The MSD Ignition features a capacitor which is quickly charged to 460-480 volts and stores it until the ignition is triggered. With the CD design, the voltage sent to the coil is always at full power even at high rpm. - Page 3 Every application is different and should be tested and tuned. MOUNTING The MSD Ignition may be mounted in any location except on the engine or near the exhaust manifold. Excessive heat at these locations may cause damage to the ignition. It can be mounted in any position.

Page 4: General Wiring Information
GENERAL WIRING INFORMATION Wire Length: All of the wires of the MSD Ignition may be shortened as long as quality connectors are used or soldered in place. To lengthen the wires, use one size bigger gauge wire (12 gauge for the power leads and 16 gauge for all other wires) with proper connections. - Page 5 INSTALLATION INSTRUCTIONS WIRING TO THE FACTORY IGNITION SYSTEM NOTE: The factory rev limiter and all timing functions will still function as normal with the MSD Digital DIS Ignition installed. 1. Locate the ignition coils and identify which wire leading to the coil(s) has 12 volts on it with the ignition key in the On position.
