I have a 67 convertible with a single pin brake pressure sensor. I have found dual pin sensors. Does anyone know where I can find a single pin. The sensor when connected to the harness always causes the light to light. The system is fine I replaced all lines no leaks. Just cant find the sensor

Are you sure the "shuttle" inside the distribution block is centered? It typically won't do it all by itself. Sometimes you CAN re-center it by sharply stabbing the brake pedal with both feet as hard as you can.... if it is, indeed, the switch, check with West Coast Classic Cougar....

Unscrew the switch and put a meter across it with the plunger depressed and not.
If it passes, the "shuttle", is off centre.

The single pin connector was a one-year item, you'll have to find used or NOS.

But, replacing it won't fix your problem. It's not really a pressure sensor at all, it is a simple electrical contact that senses when your shuttle pin is moved off-center. This happens when there is a leak in the brakes, but can also happen during normal brake bleeding. All you really need to do is re-center it.

Using this tool eliminates the chance of tripping the switch when bleeding the brakes-
