1973-1982 GM HEI to MSD Ignition System Wiring Harness
Remember to pick up this wiring harness when hooking up your HEI distributor to an MSD ignition system.
MSD Ignition Controls are easy to install, but we also offer several plug-in Harnesses. These are especially handy for quick installation on late model vehicles!
The 1973-1982 HEI to MSD Ignition Harnesses plug directly into your Corvette's factory coil and harness then four color coded wires plug into the corresponding wires of the MSD. Two wires go from the MSD to the battery and you're done with no cutting or splicing!
