CWA 50 intercooler pump for SL55
Hello together!
I bought a Pierburg CWA 50 Pump to upgrade my intercooler Bosch Pump.
My Problem is that i only have 2 cables : Power 12V + and Ground - and the Pump has 3 pins : pin1 + pin2 PWM signal pin3 -
Does anyone know how to connect the pump properly?
i was told to to connect 12V to pin1 and pin2 and - to ground. then the pump turns a bit but very slowly like an emergency programm.
I wonder how to connect the pump to have full power.
Thanks so much!!
Darius
