MSD Universal Harness

MSD offers these wiring harnesses to simplify the installation of a MSD 6 series box on late model vehicles. The harnesses plug in between the ignition coil and the factory coil connector. Four wires with corresponding colors and matching connectors then connect directly to the MSD 6 wires. These harnesses reduce the installation time, reduce or eliminate cut wires, and allow you to quickly convert back to the factory ignition.
