Here's a hot coil at a reasonable price. Same internal core as an IGN-1A, but without the built in ignitor. This one can be used for distributors or coil per plug. Use with BIP373s or an external ignition module. These are vibration resistant and can be mounted at any angle - no oil to leak out. While most coils have just two connections, this 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 (sold separately part # IGN-1A_Conn ): 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. This coil works well with the MicroSquirt, which has built in coil drivers. Note: For capacitive discharge ignitions like an MSD box, see our IGN1-CD.
