Here’s a hot coil at a reasonable price. The IGN-1 shares the same internal core as an IGN-1A, but without the built-in ignitor. This can be used for distributors or coil per plug. Use with BIP737 or an external ignition module. IGN-1 Inductive Coil is vibration resistant, can be mounted at any angle and is one of the few performance 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-1 pinout, using the pins marked on the connector
A (towards edge of coil) – Positive terminal, to battery power. B (center) – Negative terminal, wire to ignition module. C (towards inside of coil) – Secondary ground, connect to cylinder head. *Note: For capacitive discharge ignitions like an MSD box, see ourIGN1-CD.
