"I have a cut wiring harness on my 2016 991.1 Carrera 4S Cabriolet (VIN: [your VIN]). Here's what I know: The connector: A 14-pin female plug, disconnected and propped up toward the top of the driver-side rear wheel well , tucked into a recessed pocket area right next to the coil spring/strut assembly . Routing: The harness originates behind the rear seats (where the rear control modules live), runs forward into the engine bay, and splits into two branches there. One branch (still connected, working fine) feeds tail lights, rear bumper, spoiler, and cooling fans. The other branch — the cut one — is 11 loose wires that should route through an oval hole in the firewall area, down the driver-side sill, back to that 14-pin connector near the top of the wheel well. Symptom: Every center console switch is dead, and the convertible top doesn't respond at all. Important: The wire colors on the loose connector do not match the wire colors on the cut wires in the engine bay — so color-matching won't work; I need actual pin numbers/positions. Can you pull up the PIWIS wiring diagram for this VIN and find the connector matching this description? Specifically, I need: The connector's part number or reference ID (so I know we're looking at the same one) A full pin-out — every pin number and what it connects to (power, ground, CAN-H/L, or a named function) Which module(s) this connector originates from in the rear of the car. Thanks in advance.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey @kouroshnahali , a cut harness near the rear wheel well is a tough break, especially with the convertible top and all the center console switches out of action. Are there any part numbers stamped on the plastic housing of that 14-pin connector? Sometimes that can help others track down the exact wiring diagram you're looking for.
@deilenberger frequently mentions alldata.com as a great source of tech info including wiring diagrams. There are cheap trial memberships.
Thanks for the suggestion but unfortunately ALLDATA does not cover 911 only MACON.
