Hey all — working on a theft-recovery 2016
Carrera
4S Cabriolet (manual) with a cut wiring harness. Here's the routing I've traced so far:
The harness originates in the rear of the car, behind the back seats, where the rear control modules live.
It runs forward into the engine bay and
splits into two branches
at that point.
Branch 1
(still connected/working fine): feeds tail lights, rear bumper, rear spoiler, and cooling fans.
Branch 2
(cut): 11 loose wires that should route through an oval hole to a female 14-pin connector, which is now just dangling loose in the driver-side rear wheel well.
Since the lighting/fan branch is fine and only the second branch was cut, this doesn't look like a power-distribution harness — my guess is it's carrying the CAN-bus and/or module power feed for something else back there (possibly PASM, ABS sensor circuit, brake wear, EPB, and/or the convertible top control unit — all of which stopped working, along with every center console switch).
Important:
the wire colors on the loose female connector do
not
match the wire colors on the cut wires in the engine bay. So this isn't a simple "match red to red" splice — I need the actual pin numbers/positions from a real diagram, not color-based guessing.
I bought a matching 14-pin male connector to splice in, but I'm not willing to guess at the pin-out (already burned once trusting an AI-generated "wiring map" that turned out to be fabricated). If anyone has PIWIS access, I'd really appreciate a screenshot or printout of:
The wiring diagram/pin-out for the 14-pin connector in the driver-side rear wheel well, and what module(s) it originates from in the rear
The power/ground/CAN feed path to the center console switch module
The convertible top control unit's connection into that same harness branch
Happy to provide the VIN via PM to get the exact spec for my car (manual C4S, so some options may differ from typical PDK diagrams).
Trying to avoid a $1,000+ dealer diagnostic bill for what looks like a bad splice/cut from before I bought the car. Even a phone photo of the diagram screen would help enormously. Thanks in advance.
Hey
@kouroshnahali
, that sounds like a real headache, especially since the wire colors don't match on the cut harness for your 991.1. Out of curiosity, have you been able to find what that 14-pin female connector in the wheel well was originally plugged into? Adding a bit more context there might help someone with PIWIS access zero in on the exact diagrams you need.
May be the pictures can shed some light. These cut wires go to a male 14 pin(only 11 pins are used) connection that would plug into the female plug. They control all the center console buttons such as
PASM
, soft top, sport and sport plus etc. That's why I need wiring diagram to figure out what color wire goes to what pin number of the male plug.
