MSD install question

816 Views 6 Replies 4 Participants Last post by  LEVE
My setup is a 82 CJ-7, I am replacing the stock 258 with a 401 with tfi upgrade. i want to incorporate a MSD 6A module. does this replace the stock duraspark module? The MSD instructions show two wires hooking into the factory coil connector then two wires going to the coil. Don't the wires from the factory coil connector come from the duraspark module?

If you follow the diagram above you can remove the stock duraspark module.

The green wire is negative for the coil, also used on some tachometers (not for use with a tach after MSD)

Yes you can use butt splices.
