wire to ground. When the VIOLET wire is grounded, the vehicle will crank but not start.

Magnetic Pickup Trigger

When using the mag pickup to trigger the MSD, install a switch to the WHITE wire and the other side

to ground. When the WHITE wire is grounded, the vehicle will crank but will not start.
