Hi guys.

2012 Cayenne.

I need to locate the antenna wiring going to the tailgate spoiler assembly.

Anyone know where this wire bundle is routed from the roof and down to any main wiring loom?

Thanks in advance,
Tore

The wire looms are routed next to the hatch hinge through a plastic wire chase that clips to the hinge. There is a chase on each side. You will need to remove the inner panel at the top of the hatch, and the side panel to access it. Both panels are only held in place by clips, but both pretty easy to remove.

Fantastic, thank you Avec.
Cheers,

Tore, I'm moving this to the 958 subforum - since that's what you're asking about.

There are two flexible conduits into the top of the liftgate. The right-hand side (passenger) is crammed tight, as it also includes the washer fluid hose. The left (driver) side is 'less congested' but not by much. I ran a dashcam line through the left side and it was a challenge. You want to be VERY careful not to use anything sharp when trying to add to it. Otherwise you'll risk puncturing the insulation on what's already in there. I used some fridge icemaker tubing.

If you get to the point of needing to remove the spoiler, I posted a picture of the service:

I also posted about how I installed my dashcam.

wkearney99, thanks!
I have tried to remove the outer (plastic) part of the rear spoiler, and removed the outer two screws and the two nuts as shown in the pic from the Service manual. However, I was not able to remove the spoiler. It was somewhat loose on the sides, but there must be some very firm clips or something along the edge that holds it. I did not dare to pull very hard, it was not my car.

The 2011/later models seem to have a different construction than the earlier models. The antenna amplifier is placed above the car lining, and not in the spoiler. The rear windows also seem to have 2-3 embedded antenna wires, in addition to some in the spoiler plastic piece.

Cheers,
Tore
