WARNING: During installation, disconnect the battery cables. When Disconnecting, always remove
the Negative cable first and install it last.
Note: Solid core spark plug wires or non-resistor spark plugs cannot be used with an MSD Ignition
Control.
CARBURETOR
The PN 6012 Ignition Controller is designed for GM LS 2/LS 7 based engines that have been retro-fit with
an intake manifold and carburetor. The Controller is supplied with a wiring harness that connects to the
factory connectors for a simple installation.
EFI
This Controller can also be used in stock, EFI applications, by using accessory Harness PN 88862. This
Harness allows the PN 6012 Controller to tap into the sensor signals without interrupting the OEM ECU.
The ECU and Fuel Injectors operate as normal while the PN 6012 controls the ignition and timing.
OPERATION
The MSD Controller offers several programmable features that allow rpm and timing adjustments. This can
be achieved through the supplied Pro-Data+ software via a PC or with the optional Hand Held Programmer,
PN 7550. Timing adjustments and selections can also be made with plug-in modules. Software installation,
operation and the programmable features of the Controller are explained in detail in this document. More
information can be found in the Pro-Data+ Software Help section.
MOUNTING
The Controller is designed to be mounted under the hood or on the firewall. Do not mount the unit near
exhaust. Four vibration mounts are supplied to mount the unit. Find a suitable location, confirm that all of
the wires reach their connections. Mark the mounting hole locations using the unit. Drill the holes with a
3/16" bit.
WIRING
All of the wiring, except three wires, are routed into factory style connectors to ensure an easy installation.
The wire descriptions follow in the chart on pages 2 and 3.
