Buy this switch

After a total new brake system rebuild on my 46 Ford coupe, the one thing leaking was the old stock Ford brake switch (I used silicon brake fluid). The Speedway switch solved it. I learned the hard way to get the harness with it. You won't find it any place else or at least I couldn't.

3 rd try is a charm

First one leaked at the plastic element when it was new.Second one just failed, and I was driving around w/o brake lights until a friend noticed.Will be keeping an eye on this one, hope it keeps working. I have had a lot of failures of parts like this that I am sure are made in China.
