Red = MAP +5V
Black = MAP/Linear Ground
Purple = MAP/Linear Signal
F = Linear Mode
.2 Volt = 0*
4.8 Volt = 15*

Momentary Switch MUST be capable of supplying current
draw of Linelock Solenoid. If switch is rated at a lower amperage
then the solenoid, a Relay MUST be used. See Diagram for
Manaul Transmission installation for Relay wiring details.
Optional LED, On when
Arming Switch is ON.
Automatic Transmission with Linelock & Boost Retard
Retard Activation - apply +12 volts to
force Boost Retard to maximum retard
allowed by “Degrees” switch setting.
Analog Output
0-3 volt, .2 volt per 1* of Retard
Connect to analog input of Data
Recorder.

When the LNC-2000 is powered up with a MAP Sensor installed
it will switch to Boost Retard mode. The “Degrees” switch will
still set the Maximum amount of retard allowed. The “Rate”
switch will control the degrees of retard applied for each lb
of boost applied to the MAP Sensor.

Use this configuration to activate Linelock and the 2-step function using a momentary push-button switch.
Once the toggle switch is flipped ON and the momentary switch is pressed, Linelock and the 2-step function will
be activated. When the push button is released, Linelock and the 2-step function will be deactivated. Since the
LNC-2000 is connected to the MAP sensor, the LNC-2000 will be in Boost Retard Mode.
