This is an addendum to the supplied instructions that detail the function and wiring of the MSD 6BTM
Ignition Control and other 6 Series Ignitions. Review those instructions first for information and wiring
for your application.
INSTALLATION
1. Mount the Boost Control Dial where it can easily be reached by the driver. (Before mounting the
unit, ensure that the Boost Control Wiring harness reaches your desired location). Use the adhesive
on the back or the four mounting screws (use a 3/16” bit).
2. If an access hole to the engine compartment is not available, use a 3/8” bit to locate a new one. A
3/8” rubber bushing is supplied to route the wires through.
3. Route the wires to the MSD Ignition making sure they are secured away from heat sources and
moving parts. Install the supplied 2-pin Weathertight Connector to the two wires. This connection
is not polarity sensitive so it does not matter which way the terminals are positioned.
4. Connect the 1/8” tubing to the spigot of the MSD and route it to a port on the intake manifold. Use
care when routing this line not to kink it and secure it away from heat sources and moving parts.
Note: If a Boost pressure gauge is being used
(recommended), T into this line.
