Fits:1999-'03 HD® Big Twins. Carbureted only. S&S® IST Ignition Installation Kit Includes a wiring harness adapter, knock sensor, and temperature sensor.
Do not use a dual fire coil with the S&S ignition module.
This kit will NOT work with vehicles equipped with flat slide carbs,
open primaries, and dry clutches. If you want to use IST with these
configurations, contact S&S – we can help set up IST.
The S&S IST Ignition System is not recommended for kick start applications
unless a cam position sensor is used. Engines using a crankshaft
position sensor only will be difficult to kick start. We recommend our
Super Stock® ignition system for kick start applications
