Ignition Race Coil Without Ignitor for CDI Applications DIYAutoTune

Description

Here's a race coil designed for CDI applications that's small enough and cheap enough to use one per cylinder if you're so inclined. These are vibration resistant and can be mounted at any angle - no oil to leak out. Also works with capacitive discharge ignition boxes - MSD, Mallory Hyfire, etc - if you're using a distributor. While many CDI coils have just two connections, this is one of the few CDI coils you'll find in this price range to add a secondary ground connection to isolate the primary side from the secondary. It uses standard HEI type spark plug wire boots. Here is the IGN-1CD pinout, using the pins marked on the connector (sold separately IGN-1CD_Conn): A - "Positive" terminal, wire to the terminal on a CDI box used for coil positive B - "Negative" terminal, wire to the terminal on a CDI box used for coil negative C - Secondary ground, connect to cylinder head. For example, if you were wiring this to an MSD 6A, you'd wire the orange wire to C and the black wire to B.
