To use an LED bulb for the O/D 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.
Shift-in-Progress
The shift-in-progress output is used to implement torque management
functionality during shifts. When a shift is occurring, this output will be pulled to
ground as a signal to the engine management system or ignition timing control
device to reduce torque by managing ignition timing, throttle plate angle, boost
pressure, or, for diesel engines, fuel. In some cases, a "pull-up" resistor to 5V or
12V may be needed to provide the proper input to the controlled device. Please
contact US Shift tech support if you have any questions regarding the
connection of this signal.
