Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Suggestion
I seem to recall if you want the switch, you have to change the relay to the one for switched PSE.
Leading evidence: 'Replace relay' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace relay' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

I pulled the batwing out to install a new stereo on my new-to-me 02 C4S and found that one of the blank switches actually had a spade connector behind it. Seems to be running off of the cigarette lighter wiring so I assume it�s a mod from a previous owner, but I�m confused how it ended up in that state.
Anyone recognize this approach as a common mod, or perhaps recognize it as factory even?
This. My 2002 targa has PSE but did not have a dash switch. However the wiring was already there, behind one of the blank buttons in the horseshoe. All I had to do was get a switch and plug it in.
I think you guys have nailed it. I don�t have a rear wiper and there�s no hole, but the car was listed as having PSE however there is no switch for it anywhere.
Can you confirm that the switch let you turn it off instead of on? (Obviously it can do both, just wondering if installing a switch enabled louder or quieter) I can�t see why they�d have it off in the default state and not provide a button but just want to be sure.
From the 2003 Carrera manual - PSE Operation - and keep in mind - that when on - there are specific times when it automatically goes into off state.
Sports Exhaust System
The sports exhaust system can be switched off or on when the ignition is switched on.
If the rocker switch is not operated, the sports exhaust system will be on when the engine is
started.
Depending on the vehicle equipment, the rocker switch may be installed in the centre console or
in the centre tunnel behind the ashtray.
Switching off
I> Press the rocker-switch symbol. Indicator light comes on.
Switching on
I> Press the rocker-switch symbol again. Indicator light goes out.
Light on: PSE is closed at all times
Light off: PSE open except between 30 & 45mph. You can disable this feature by modifying the relay.
It defaults to the open position when starting up.
Also, PSE would only be the black connector. The white one is something else.
The PSE for 996.1 did not have a switch. Only the PSE offering for the 996.2 had the switch.
In both cases, there was a relay and small logic board. The switch connects to that.
I never heard of a 996.1 with PSE that isn't retrofitted? As far as I know PSE became available with the C4S.
And the ones without switch should have a different version of the relay on the logic board. I seem to recall if you want the switch, you have to change the relay to the one for switched PSE.
reduce costs of the wiring harness. cheaper to make one version and sell the plug in switch as a premium since most buyers would be unaware of the prewiring
It can also be disabled (always open) by capping the vacuum line at the Y connection to the right the rear latch. And the cap stores perfectly in the snuff cone in the ashtray when it does occasionally get hooked up.
No kidding! Maybe that explains why my PSE occasionally loses its mind and sticks in one mode or the other. It's easy to fix so I just live with it up until now.
This is a source reference. Confirm exact model applicability in the original material.
