C3 Corvette Ignition - Distribution Of Power

MSD's Blaster 2 coil is a direct replacement for the tired, old stocker. Simply bolt it in place.

Wiring is a piece of cake with MSD's included harness. It requires only three wires: red to coil positive, orange to coil negative, and black to ground.

With the terminal connections complete, plug the three-wire Weathertight connector to the distributor harness. Note the temporarily unused green wire. It supplies the needed signal to an electronic tachometer.

After consulting the directions for your ideal timing curve and rev limit, you can install the MSD distributor cap.

MSD also pitched in a set of 8.5mm Super Conductor plug wires. They are available in pre-terminated custom-length sets, or you can do as we did and make your own.

Beneath this plump plug boot is MSD's proprietary dual-crimp terminal. These are so secure that MSD warrants them against pulling apart for a full five years.

Lay out the wires as you wish. We chose to use the factory routing tabs on the valve covers, and it worked out nicely. The wires will need to be cut to the proper length before you install the terminals and boots.

Once the wires have been cut, you can strip the insulation using MSD's Pro-Crimp tool.

As the name implies, the Pro-Crimp also does a fine job at terminal crimping.

With the terminal properly crimped, you can slide the boot in place. A shot of silicone spray can make this easier.

Once you have the process mastered, it will only take you a few minutes to finish all eight plug wires and the coil wire. Install the wires as you complete them to keep from crossing them up.

You can reinstall the factory chrome shield if you wish, or go au naturel as shown here. Once you've got everything buttoned up, fire up the engine and set the initial timing. A dyno tune or a trip to the track is the best way to ensure you're extracting maximum performance from your new electronic ignition system.
