Finally diagnosed the light problem on my 66 911: the brake light switch. When I replaced the master cylinder [for a dual circut] the new one came with a switch, but it was only a single prong. the old switch [broken] was a dual prong make or break circut, but the new switch [i think] just grounds out the lead in when oyou touch the pedal. Looking at my setup, it doesnt look like i can get this new switch to work, so does anyone know where I could find a 2 prong switch to buy? I've already tried pelican and porsche parts direct, any other places to look?

anybody have an old one they want to get rid of?

random: The single prong will work, just tape back the brown wire. Also, make sure your reset button (under the black rubber) at the end of the switch is in the correct position or the brake lights won't work (or something will happen with the warning light - I can't remember which).

I believe the two prong switch is a common VW Beetle part. I got mine at a Bug specialist shop for about $10.

A while ago I saw several on ebay. I got mine form Autozone but the distant between sprongs are diff. I had to modified it to fit, but works
