Surprisingly I found zero information about using a Mirror Tap on the Macan. Seems most people were running a harness down to the fusebox, which seems like a huge PITA. Having installed Mirror Taps in other Porsches (and other makes) I have owned I was pretty sure it was possible. So I tackled the project and took photos, hopefully this will help others. As far as I know all Macan generations should be the same.

1.) You must remove these 3 panels in the order they are numbered 1-2-3. Reinstallation is the reverse order of removal 3-2-1. Tip the mirror all the way down to maximize clearance.




2.) The center panel w/ the passenger airbag light can be easily removed by just putting your fingernails on either side and carefully pulling downwards. (Ignore that the main panel is already removed, I took this photo out of sequence).
IMPORTANT: DO NOT UNPLUG THE CONNECTOR FROM THE BACK OF THE PASSENGER AIRBAG LIGHT - Just let it hang. If you unplug it you could get an Airbag fault. If you do it's not the end of the world, you can just have the dealer clear the fault code and reset the airbag light, but it's avoidable.


3.) Remove the rear view mirror ball stalk cover. This piece is in two halves. There is a small opening on the forward seam you can insert a nylon pry tool and twist. This takes a bit of effort, be careful, but it's not hard. Importantly you want to take off the passenger's side first, then the drivers, due to the way the tabs are oriented to avoid breaking them. Reinstallation is the reverse of removal....put the driver's side on first then snap the passenger's side into it. Remember you must have the center panel w/ the airbag light off in order to get the stalk cover off/on b/c it goes underneath it at the back edge.


4.) Remove the main roof console panel bezel by starting at the windshield end and gently pulling downwards with your fingers. Work your way backwards separating the tabs. This was very easy to pop off, just be careful not to bend the bezel as you work your way around.


5.) Now for the tricky part. Getting the main roof console panel down. I saw lots of posts about removing this on Cayenne forums and everyone seems to manhandle it and bend the metal clips. You can get it off without any bending or damage. With a thin nylon pry tool slide up between the panel and the headliner and push the clips in as you work the panel downwards. These little indentations I am pointing to correspond to each metal clip.


6.) This shows where you are trying to put the thin nylon pry tool. The main roof console panel is hinged at the front, so start at the rear/center and progressively release each clip w/ one hand and the pry tool while using the other hand to keep downward tension on the panel. Once you get the first 2 clips the rest is easy b/c you can now see each clip.


7.) The main roof console panel is hinged at the front. Once all the clips are released it will hinge forward. You can lift the hinge tabs out of the cradles to free the center panel once it's rotated down and forward.



8.) Let the main roof console panel and the center airbag light panel hang by the wiring harnesses, they are not heavy. The connector you want to tap into is the BLUE connector. This is the connector for the rear view mirror.


9.) Pull the blue connector out of it's holder.

The wires are as follows (at least on my 2022 Macan GTS, Porsche may have changed wire colors on different years/models as they often do, so check w/ a multi-meter):

Mirror side of connector: Blue +12v switched / Red +7.5V - variable, assume this is for the auto-dimming / Brown Ground
Vehicle side of connector: Red-blue stripe +12v switched / Black-yellow stripe +7.5v variable / Brown Ground


10.) I chose to tap into the mirror side of the connector b/c that was the side I was going to run the MirrorTap harness out to where I wanted to mount my radar detector.
Tap was to the blue wire for +12v switched power and brown for ground. After putting the taps into the connector I zip tied the MirrorTap harness in place so it would not pull out and snapped the blue connector back into it's holder.


11.) Prior to closing things up I tested to make sure the power was good and it went on/off with the ignition.


12.) When reinstalling the main roof console panel make sure you get the hinges back into palace first, then rotate the main roof console back into place.


13.) Everything back together w/ the Mirror Tap routed out between the middle airbag light panel and the main roof console.


14.) Mounted the detector w/ stick on mount in position as high/close as I could get it into the designated "toll pass" area for those of us with Thermally and Sound Insulated glass option, where electronic signals are supposed to be able to pass through.


15.) I also chose this mounting position so that I can use my sunshade w/o interference. I tried a Blendmount I had left from my GT4 (same mirror stalk) and it hangs down too low for the sunshade (plus not a good spot if you have the insulated glass option).



All done! Hope this helps someone. I was surprised the Macan has been around for coming up on a decade and there is almost no info on the interwebs about using a MirrorTap that I could find. Cheers!!
