Spare port to control relay
Are there any spare ports in Gen3 PCM that can be used to control relay. I want to add trans fluid radiator fan and was wondering is it possible to control by PCM? As far as i remember id toes read trans temp fluid.
Best regards

There are unused pins on the PCM, however there is no logic in the OS to make use of them. You will not find any table or parameter to turn the fan on/off.
You need a custom operating system to enable that function. It is possible with the correct code but i doubt you will find anything
