Hi, I want to trigger a gpio rabsberry pi when car is park gear.

Can anyone help me with which fuse would help me detect this event?

 

I have no idea what you are trying to setup. Can you tell us more? Also the year along with some basic information on your car would help.

A single fuse won't be assigned to just park on your gear selector.

 

Thanks for responding
Openauto pro on raspberry pi starts when
the car is turned on.

But I need a trigger that would turn it off too.
I want to avoid a solution where a always on relay sends a trigger to rpi when car is turned off.

So, alternatively I was thinking that maybe I can trigger this when car goes into P gear.

Your gear selector switch is wired directly to the powertrain control module, so I would not suggest tapping into that wire.

Some fuses are powered only when the key is turned from the off position. You should be able to have a power signal from one of the switched fuses to turn on/off the unit. I don't have a 2012 wiring diagram, but you can use a volt meter or test light to see which fuses have switched power.

You should have empty fuse sockets that could be used as well. Older accords had an accessory fuse that may work. Since I don't have a wiring diagram, I can't verify.

 

Hmm, I am rather looking for a trigger to turn off (not turn on raspberry pi).
Typically a driver goes from drive to park and I was trying to tap on this event.

 

I should have phrased my previous response better. Some fuses only get power when the key is turned on, and power will be turned off to the fuse when the key is turned off.
