Fans run constantly and no knock signal

Hello again, I have a 1998 wrx sti with a g4+ plug and play. The fans are running constantly with key on. I am finding it hard to get a stock wiring diagram for a jdm car. The fans worked fine with the factory ecu. i have messed with every parameter and ecu setting for the fans. There is fan 1 and fan 3 setup from the supplied plug and play setup.  I also dont have a knock signal showing.

The main things to check will be the 'Polarity' setting on the Aux Outputs the engine fans are assigned to

Another thing to check is that the Engine Fan Settings are appropriate

If either of the engine fans is set to come on with Air Conditioning check if the Air Conditioning request (on a Digital Input) is active.

For the Knock control, have you gone and set this up? The standard base-map will not have this enabled.

Scott.
