Porsche 928 Power Window Switch Bezel Replacement Alternative to Factory Switches

This model provides a clip-in switch panel to accomodate an inexpensive, modern power window and sunroof switch for the Porsche 928.

The switch used is a cheap chinese switch, model pictured.  They can be purchased off AliExpress (https://www.aliexpress.com/item/1005010790075441.html), but also Amazon, eBay, and various other places for under $10 each.

The replacement switch is a 6 pin unit (unlike the factory 4 pin unit).  No problem.  Wire the pins on the new switch as follows:

Pin A: Factory Red Wire

Pin B and C: Factory Brown Wire (will need to splice the factory wire into 2 and run brown to both pins on the switch)

Pin D: Factory Green Wire

Pin E: Factory Black Wire

Pin F: Not used (can run to a switched instrument panel illumination power source if you want them to light up, but this is optional).

If you have issues with your windows operating in reverse, you may need to swap the green and black pins on your switch or in the loom connection under the dash.

The wires will need to be soldered on to the posts in a low profile manner (like the factory switches) in order to clear the transmission tunnel (see pics).  I strongly recommend insulating the connections with heat shrink to avoid shorts.

Panel clips in to the holes left by the removal of the facotry switches.  Be gentle with it as the mounting tabs are fragile (depending on filament used).

All factory switches need to be removed for this to work.  This includes the rear wiper switch.  My car has no rear wiper, so that isn't a problem for me.  You could always add in another switch for the wiper if you like - it is a simple on/off switch (momentary).  Up to you - the space is there for it.

Print face down.  You may wish to add supports for the switch mounting bars inside the apertures, as the bridge may be an issue (depending on filament choice/print settings).
