Brake Light Wire
Although not necessary, the wire labeled “brake light” should be run to a factory brake pedal switch (NC) so the TCC will
unlock when you apply the brakes
1.4.2 Outputs
Overdrive Cancel Indicator
This output is driven when Overdrive Cancel is selected. It can be used to activate an LED to indicate that Overdrive
Cancel is in use.
Spare Output (unterminated)
This output can be congured for other indicators such as TCC Status, Dyno Mode etc…
Speedometer Drive
Some speedometers may not be driven correctly by the normal speedometer output of the TCU. In such cases, a digital
output may be programmed to output the same speed signal. The default is 2000 PPM. This value can be modied in the
Tuning Software if needed. Under the Hardware Setup/Speedo Output Settings Window. Reference Figure 8.
