The diagram I have came from Porsche PIWIS for a MY2009 Cayenne.

So either the diagram is wrong or your car is not a MY2009. Can you PM me the VIN?

Loren,

The pic. send by temporel looks not comprehensive enough for details (exact routing), but perhaps the wiring colors will match with the SERVOTRONIC steering rack connector instead of the RDK system?

Here is the Servotronic

RDK (TPMS) control unit

i loren i'm not sure but it's not servotronic i give you an another picture on front of my cayenne where you will see the wire tks again

Maybe RFM knows?

Small detail to start with, you talk about the front LEFT but the pic. shows the front RIGHT. Best you can do is following the wiring or ask for a PIWIS Cayenne electric diagram print out, could be anything with 3 wire connector on the right side from chassis acceleration sensor till loading sensor (headlight height correction HID). Success.

hi rfm sorry it's right side...the dealer give me all this info he tell me that the wire is for tire pressure sensor but the thing is the wiring color is not the same as piwis and don't want to help me more. so if some one have a cayenne 2009 and want to look at and give me a pic or is wiring color with pin tks you very much.

I don't think that wiring harness is for the RDK as I believe the antennas run in the front area of the wheel not the rear.
