Lingenfelter L460050000 Lingenfelter STOV-002 MPH Activated Switch v3.5 - Manual (Page 10)

Page 9 of 12
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 CPP (Clutch Position Switch) and unplug 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 CPP connector.
4 - Splice two wires onto remaining CPP connector wire and connect one wire to #85 on Relay.
The extra wire will be used for LNC-2000 Launch Controller activation.
5 - Connect terminal #86 on Relay to Ground.
6 - Connect wires cut from CPP Switch connector to Terminals #30 and #87 as shown.
