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?

Thanks
Max

You can hook it up two ways. Using the factory ignition to trigger it through the white wire or using the purple and green wire to get a signal straight from the distributor and unhook the factory ignition. The latter one is the one I did.

Here is how I wired mine

That's how I wired mine too. Thanks for posting the diagram.

So, just to clarify, I leave my stock module in place and hooked up except for unhooking and taping up the two wire connector.

the green wire on the coil connector is not used at all? I am talking about the connector in the upper right hand corner of the diagram. I can cut out the coil connector and just use a butt connector to hook up the reds?

Thanks for your help,
Max

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.

[/ QUOTE ]1. It's not a bad idea to leave it in place.
