Not sure what's needed to make them work for an application like this, but when I was running stand alone power for: starter, fuel pump and fans; it was too much of a PITA to use factory switches.

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.

I've done tons of research on Rennlist and via google, but need some more information. I'm looking to install HP-905 Blinder laser jammers. Great product, I had it installed on my 135i, zero tickets during the 1 year I owned it.
However, I would like to do a "cleaner" install on the 996, with nothing visible in the cabin. I'm hoping to use one of the dead toggle switches on the dash (below PSM on/off) as a kill switch (jam a LEO, slow below speed limit, switch jammers off for LEO to get reading). Based on the info I've found this seems to be possible, but I would like more more info before getting everything pulled apart. I'm assuming the blank switches are not wired to anything, my plan is to get power through an empty slot in the fuse box, with the switch between the fuse box and my jammer control unit. I can then power it on/off via that switch, leaving the unit in jam behind the dash.
Has anyone does this or something similar? Any advice is appreciated, thanks!
I haven't installed a jammer, but I have used switches for other things (i.e. controlling a garage door opener.)
The blank "switches" in the dash are just plastic blanks, not actual switches. You can purchase replacement switches, but there are different types depending on their original intended use. Make sure you understand the pinouts and how the switch works before ordering.
Most are just "momentary" switches, so in order to use it as an on/off switch, you would need to wire up to a separate relay in a latching circuit.
As far as aesthetics, you can sand and paint over any switch, in case it comes with a graphic printed on it that you don't like. Some are also illuminated.
For power, go to the 4-port phone connector that is in the 996 center console (usually behind and below the radio.) That's an easier place to get power, instead of the fusebox.
My 996 did not have seat heaters, but had a two button "batwing" with blanks. I have used the blanks to mount USB and Ipod jacks. Don't see any reason you couldn't mount the swith "down low" in the batwing. Relatively easy to get to, and don't think many would even look there. You could even "camo" the switch.
Most of the switches in the center console are not simple on/off switches. Not sure what's needed to make them work for an application like this, but when I was running stand alone power for: starter, fuel pump and fans; it was too much of a PITA to use factory switches.
I have my radar detector wired via the 'switched side' of the center pickup by my right foot. It only comes on when I have the ignition switch on. That way I never forget to have the detector running when the car is moving.
I ordered a defroster switch off Ebay, am going to attempt to add this into my system. I could not find a powered fuse controlled by the ignition, meaning my jammers stay on even when the car is off. Optimally, it would come on when the car is on and go off when I turn it off.
I think by interrupting the wiring coming from my fuse box, going directly to the jammers, I can add in the switch, allowing for a simple on/off.
Look for the four wire "phone prep" plug laying behind your Cubbies in the center console they just snap out, top one first.
