For those who specified dash cam prewiring for their new Porsche we now have more info about what u get for your money.


Prewiring provides a proprietary connector in the courtesy light overhead console which has a ground, constant 12v and switched 12v.


If u r using the Porsche dash cam this comes with a harness that plugs into the connector and the power supply side of things is plug and play.


I am going to use this connector to power an aftermarket dash cam and my radar detector - so I will adapt the Porsche harness to provide me with what I need.


The Porsche harness is part # 9Y0-044-955-A and costs about $32


This will eliminate using the mirror tap and will provide dedicated fusing for your attached devices.


I just compared the camera wiring diagram to the harness connections


I have a cabriolet and there are only 3 wires entering the prewired connector.

It's my understanding that when u order from your dealer and provide your VIN the coupe package comes with front and rear camera and appropriate harnesses. If you have a cabriolet you only get the front camera and harness.


The prewired female connector connections in the overhead console are


Red/White is 12v hot all the time

Brown is Ground

Black is switched 12v


The camera harness connections are


Red 12v all the time

Black is Ground

Green is switched 12v


These connections don't matter if you are simply connecting a Porsche camera to the prewired plug.


If you plan on making your own harness you need to confirm these "pinouts".


Utilizing this connector eliminates the need for a mirror tap and will provide a dedicated fuse for your camera and / or radar detector.

The camera in the last picture on the left side looks similar to Porsche's dash cam but I'm thinking it's not since you mentioned using an aftermarket camera. Is the device next to it a rear camera?

Sorry to confuse the cameras shown are Porsche OEM - when you order the camera kit it includes the harness.

However, the harness can be ordered separately to enable modifications

Up until now we really didn’t know what prewiring consists of.

It’s basically a harness running from the fuse box to the overhead console - provides 12v by means of a female connector that I plan to utilize for stuff other than the Porsche camera

Got it. Thanks!
