cheers,

I just ordered the wiring harness online that connects to this connector - I plan on modifying this harness to make my own that will provide power to an aftermarket camera and my Uniden RD.

This way a mirror tap will not be required.

If I need to step down to 5v I will use a 12v to 5v converter

If I need to step up to 12v I will use a 5v to 12v inverter

The Porsche wiring harness part number is

9Y0-044-955-A - Cable Set For Camera $33.20

I’m kinda wondering if a mirror tap might be simpler/cleaner/easier? Sounds like you may need a voltage converter and some sottering work to graft into the proprietary connector. Thoughts?

Radar detectors use a 12v feed which the mirror tap provides. Nothing wrong with mirror tap except u r tapping into a circuit not intended to supply another device. Corvette owners have reported issues and fuses blowing when using mirror taps.

The Porsche prewiring provides a dedicated circuit and fuse for the Porsche accessory so there would not be any impact to other components.

Interesting that aftermarket dash cams work at 5v the Porsche camera wiring harness provides 12v to the camera connection base. I don’t know yet if the base drops the voltage to 5v or the camera requires 12v to operate.

The cabriolet has very limited space behind the courtesy light compared with the coupe since the cabriolet latching mechanism takes up a chunk of space in this area. I could have packed the harness in the space under the plastic cover, below the courtesy light, but I chose not to since I don't plan on using the Porsche OEM camera. I also determined that the camera dock for the Porsche camera, in typical Porsche fashion, uses a proprietary connector not a USB C connector, so I couldn't use the dock to supply an aftermarket dash cam. So I hacked off the male connector from the Porsche wiring harness I purchased and used this to connect the female connector behind the courtesy light panel. I used this to provide switched 12v to my radar detector and to a 12v to 5v converter which will power my aftermarket 70Mai dash cam.
