MSD 6AL Wiring Diagram: Everything You Need to Know

If you are a car enthusiast or a mechanic, you may have come across the MSD 6AL ignition box. This device, produced by MSD Performance, is designed to provide high-quality ignition control for race cars and street machines. In this article, we will take a closer look at the MSD 6AL wiring diagram and how to install it.

What is the MSD 6AL ignition box?

The MSD 6AL is an ignition box that provides multiple sparks to the spark plugs during each firing cycle. This results in improved combustion, better throttle response, and increased power output. The 6AL is compatible with most 4, 6, and 8-cylinder engines and can be used in both carbureted and fuel-injected systems.

The 6AL features an adjustable rev limiter, which allows you to set the maximum RPM at which the engine can operate. This is particularly useful for race cars, as it prevents over-revving and potential engine damage.

MSD 6AL wiring diagram: How to install it

The MSD 6AL wiring diagram is fairly straightforward and can be completed by anyone with basic knowledge of electrical wiring. Before proceeding with the installation, make sure to read the instructions carefully and consult a professional if you have any doubts.

Step 1: Mount the 6AL ignition box

The first step is to mount the 6AL ignition box in a suitable location. It is recommended to mount the box away from heat sources and moving parts, such as the engine or exhaust system. The box can be mounted using the supplied brackets and hardware.

Step 2: Wire the power and ground

The next step is to wire the power and ground connections. The red wire should be connected to a switched 12-volt source, such as the ignition switch or fuse box. The black wire should be connected to a good chassis ground, such as the battery negative terminal.

Step 3: Connect the magnetic pickup

The magnetic pickup is responsible for sending a signal to the 6AL box to trigger the ignition. This wire is usually connected to the negative side of the ignition coil or to the tachometer output wire. Consult your vehicle’s manual for the correct location.

Step 4: Wire the distributor

The distributor wires are the most critical part of the installation. The positive side of the ignition coil should be connected to the red wire of the MSD 6AL. The white wire of the MSD should be connected to the points or electronic ignition output of the distributor. The green wire of the MSD should be connected to the negative side of the ignition coil.

Step 5: Set the rev limiter

The final step is to set the rev limiter to the desired RPM. This can be done using the small rotary dial on the side of the 6AL box. Turn the dial to the desired RPM and tighten the set screw. This will prevent the engine from over-revving and causing potential damage.
