Manual Mode Switch
The Manual Mode switch can be used to turn manual gear selection on or off.
The switch can be a latching switch (toggle switch, latching push-button, etc.) or
a momentary type switch (spring-loaded push-button switch, spring-loaded
toggle switch, etc.) connected to +12v ignition-switched power and pin 4 (brown)
of the vehicle harness. (The tan wire on pin 12 is for VSS output and shouldn’t
be confused with the brown wire on pin 4 for the manual mode switch.) A
momentary switch is needed to use more than 2 states. Optionally, you can add
a light bulb b12v ignition-switched power and pin 2 (white) of the
vehicle harness. This lamp will normally light up when manual mode is on. Also,
without adding a switch, a single-click of the controller’s knob can turn manual
mode on and off. This setting can be configured under the “Flex-Shift” tab of the
tuning software and “Dual Mode Auto / Manual Range Assignments” is chosen
from the pull-down menu. Whenever the O/D or manual state is changed, it will
be reflected in a change of the PRNDL indicator on the home screen display
(e.g. RNOD21 will change to RN4321).
The FLEX-SHIFT Settings window. Auto/Manual settings are at the bottom.
To use an LED bulb for the manual mode light (without built-in resistors for 12v),
connect the cathode (-) lead to the white wire on pin 2 of the vehicle harness
and the anode (+) lead to +12v ignition-switched power. Put a resistor in series
on either side. We recommend using a 1.2k Ohm resistor, but you can use one
with a lower resistance to make the LED brighter or one with a higher resistance
to make it dimmer. It’s best to stay above 1k Ohm to protect the LED. A 1/4w
resistor or higher is recommended.
