If you have a 3 speed OD trans you can use the aforementioned switch along with the other electrical components. The electrical components required to operate an OD in the factory configuration are: Solenoid, govenor, relay, KD switch, and wire loom. A manual pull cable is also required. The KD switch is normally mounted on or near the carburetor linkage. The OD trans uses the same 3 speed shifter components.
