In this configuration, the STOV-002 is being used to only allow a 2-step controller to be active
at the line. Once the vehicle is moving, the STOV-002 switches the relay, disabling the 2-step
controller. Set the MPH switch point to a speed below your first gear shift point.
1 - Locate the CPP (Clutch Pedal Position) Switch and unplug the 2-wire connector.
2 - Cut wires appox. 3" back from connector.
3 - Find +12 volt Key On power source and connect to one wire of the CPP connector.
4 - Splice two wires onto the remaining CPP connector wire and connect one wire to #85 on
the Relay. The extra wire will be used for LNC-2000 Launch Controller activation.
5 - Connect terminal #86 on the Relay to Ground.
6 - Connect wires cut from CPP Switch connector to Terminals #30 and #87 as shown.
7 - Set the STOV-002 MPH switch point to a speed just below your first shift point.
