Wire colours for auxiliary outputs
All STINGER 4 ECUs have 4 programmable auxiliary outputs that can be used to control many different items such as thermo fans, water sprays, idle motors, etc. They can be programmed to output a pulse width modulated (PWM) signal or a digital (on/off) signal. Each output can also be programmed to reverse its output signal logic.
Example of auxiliary output connections
NOTE: All outputs actually connect to ground. This means that any device being controlled must be connected to power at the positive end and to the ECU output at the negative end. Each output can sink up to 1 amp.
