Sorry about that was not sure which to use. Will do that in the future.
I have it all in now and did not eve cut a single wire 😊
I will take some video and pictures of it and post a link.
Was not able to get that panel back in for now will work on that in a future date. Getting to hot outside now.
The panel will need a bit of clearance work done as well as some carpet but not much.
The arm of the switch hits the side near the clutch and stick out past the carpet a bit but the body of the switch tuck nicely in the area just below the brake pedal.
Oh and colors are accurate at least on this 72.

I'm not sure I trust the colors shown in the diagram. Your switch should go between the wire that is hot (whenever the key is ON) and the wire that lights up the brake lights when you connect it to the hot wire.
If you figure out a good way to install a mechanical switch, please share it with us.
Reliability of modern switches has certainly been a problem. I don't know the root cause, but they are cheap and easy to replace. If you do the replacement quickly, no bleeding is necessary.

Hmmm, I never noticed a reaction time problem with them, but it's usually hard to watch your own brake lights.
BTW, there's no point in sending list messages to more than one list address; that just causes your message to be sent out more than once. The only one you need is type3 at vwtype3.org.
