Question 955 Turbo single battery wiring diagram

Any help specifically looking for what the wiring is under the drivers seat carpet and passenger carpet areas. Looking for a problem with warning for abs & psm, also air suspension faulty but yet it still goes up and down.
The gear indicator on instrument panel shows gear indication but stops after 20-30 min of driving.
Also Headlight stop working after an hour drive but work when the car is restarted. Headlights work correctly when at idle for 3 hours in the driveway.

Unfortunately the P service manual is not formatted in a logical sequence.

Cayenne wiring diagrams are divided into subsystems. ABS is one set of diagrams, air suspension is another, etc. It may or may not provide the location of modules, relays, etc.

From a former bench Tech, who was accustomed to troubleshooting equipment to the component level, its frustrating.

A Cayenne with multiple warnings is typically due to corroded wiring harness connections, caused by water leaks,

Thanks, I have a feeling it has to be a part of the wiring harness under the drivers carpet, I've already fixed drivers door and brake pedal warnings by soldering some of the wires but not finding else that looks corroded jumping out. Have no idea why they thought they should spice wires under this area should have been wired though the center console.
