CJ5 Factory tack to MSD6A

What wires off of the factory tack do I need to use to get my tach working with my MSD6A box? Thanks.

Try this diagram and your factory tach will work...



The large RED wire that USED to supply current to the ignition module & ignition coil,
But is now only used to supply an 'On' signal to the 'Small Red' MSD wire is where you hook up the tach adapter...
Along with the tach adapter 'Ground' and Tach Adapter 'White' wire that will plug into the 'Tach' terminal of the MSD CDI module.
