O-320, Bendix Mag, Ignition Harness

O-320-A1A w/Bendix S4LN-21 Mags

I'm replacing the ignition harness on my plane.

I ordered an ACS Shielded Ignition Harness from Aircraft Spruce,

Part Number 12301-22

This is the one specified for an O-320 with Bendix S4 mags.

There is a note: "Standard harnesses for the Bendix S4/S6 mags are fitted with a male nut which screws into the threaded outlet plate on the back of the mag. Harnesses for old style Bendix SF4 and SF6 magnetos are fitted with female nuts."

Since my outlets plates are not threaded for male or female nuts, where do I go from here?

Thanks,
Glenn
