You're right. See my other post.

The simple way to get this all working again properly would be to buy 2 new late switches (~$6 each) and get a late switch harness which would replace the early one you have. These are all easy to install once you jack up the car. Then you would have brake light switches AND a working warning light. OTOH, the Brazilian switches that are available now don't tend to last long and everyone seems to agree that the old switches seem to last forever. On top of that, the warning light doesn't do much good; it only tells you a problem AFTER you've already felt your foot go to the floor and you've already started to panic. Not really a good time to flash a red light in your face.... ;-) I have some late harnesses and Brazilian switches if you want to go that route. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
