Bill, now that I think of it, depending on whether or not you needed totally separate signal paths for your two circuits, it would be pretty easy to modify the 944 defroster switch to throw a voltage to two different poles.
For example, if you just needed to see a 12V, or 7V or whatever on both output poles of your switch, you could cut out the LED and resistor of the 944 switch and solder a thin wire in its place. As long as you didn't need two different voltages, it would work. I attached a quick photo of a schematic of the switch and the necessary modifications below. The stock switch is shown on top, and the modified switch below. The numbers on the schematic is the pins for each switch.

Bill, the part number that you last listed is for the rear wing and is a momentary switch. The proper switch for the rear wiper is 993.613.129.01 01C and should work for this application. It is just a straight up SPST switch.
I included a picture of the rear wiper switch in the picture below. The rear wiper switch is in the center, with the rear spoiler switch on the left. You can see the schematic and part number of the wiper switch.
In my experience, you can't change the lighting on the 944 hazard unless you open up the switch and physically re-wire the LED to the other contact pad inside the switch rocker. I actually did this on one switch because I din't realize that it was a normally closed switch. There is precious little room in there and it took forever. There is no way to use the existing contact poles on the bottom of the 944 hazard switch to have it light up when closed.

Hi, do you happen to know the pin layout to enable the light? I’ll be using this exact switch to manually enable the high-speed oil cooler fan (fan enables when the circuit is open).
