Installation Tips

IMPORTANT! FAILURE TO FOLLOW THIS WILL RESULT IN DAMAGE TO YOUR DISTRIBUTOR!

Before installing the UNILITE Distributor, make sure that your vehicle is equipped with an ignition ballast resistor (or loom resistance wire) in the wire between the ignition switch and the coil (+) terminal. Check a service manual for your vehicle to locate the ignition ballast resistor (or loom resistance wire). If your vehicle is not equipped with an ignition ballast resistor, install a Ballast Resistor Part No. PN 8214 in the wire between the ignition switch and the coil (+) terminal. Failure to use an ignition ballast resistor will eventually destroy the UNILITE Ignition Module.

I have this on a blown flathead with a serpentine belt system. It's small diameter fits perfect behind the belt. I have a MSD electronic ignition and boost controller with a mallory performance coil, this distributor was a breeze to wire up, works great and looks good!
