Thunderbolt ignition adapter harness for aftermarket ignition box?
I'm installing a MSD 7 and am trying to find out if there is a harness available that will plug into the factory
Mercruiser harness plug for the Thunderbolt ignition. This would be a cleaner install and I could easily dis-
connect the MSD should it fail and could reconnect to the Thunderbolt module.
Thanks

why not just hard wire the MSD7 into the existing harness and then just cut the purple ign wire going to the ThunderBolt ign and install a double pole double throw on/off/on switch splitting the feed....this way its all looks clean...and instead of having to connect or disconnect plugs you just throw a switch to power up the other ign system.
