2016 Pioneer 1000
I want to install a toggle switch so I can turn the fan on when I want.
Does anyone know which is the trigger wire from the PCM to the fan control unit?
There are 2 possibilities from what I can tell.

There are 2 possibilities from what I can tell.
- One is marked FanC terminal A22 at PCM.
- The other is Fan-Return terminal A33 at PCM and marked Lock on the fan control unit terminal A4.
- Also would like to know if the PCM sends a positive or negative signal and the voltage sent to the Control unit.
- I suspect that it may be terminal A22 FanC terminal If C stands for control.
- The A33 fan return may be a feedback line.
- I could open up wiring and do a functioning test to try and figure it out but thought there would be someone on here that could save me a lot of time. Thanks
