3. Disconnect the electrical plug on each coil pack by squeezing the tabs on the connector. That will allow you to completely remove your factory coil packs to make room for the MSD Ignition
coil packs' installation.

into each cylinder the same way the factory ones were installed. Reinstall the 7mm bolts back on to each plug and reconnect the electrical connector. Reconnect your negative battery terminal. Start your Mustang and make sure it is not misfiring. Your installation is now complete!
