    First, i'm new to the pro mag world.

    I've had a Mallory SupermagIII for years.

    In the past i have used a plunger switch to ground the mag. I can't recall the brand of the switch.

    All the MSD wiring indicates you need a 2 wire switch. Should i replace my plunger with a 2 wire toggle like MSD recommends/sell?

    Are you using a timing control such as a MSD GRID?

    Not a fan of the MSD relay switch. The Johnny West air deal is about the best on the market, in my opinion. I know a lot of people who have used the Mallory/FIE deal too.
