Brake switch on Superformance S1

[Driven]

We purchased a S1 about 2-3 weeks ago, it had something close to +2000 miles on it... we have driven it maybe 150mi since owning it.

 

And not a single time have we decided to make sure the brake lights work, until today.

 

 

Well, they don't. Oddly enough, there's no switch at the pedal assembly. Not even any wiring. Fuse checked out ok. Haven't checked the bulbs.

Here is how Off Road SHO's looks:

Ours is barren and void of any switch on the brake pedal.

 

I followed the front brake line from master to calipers, no pressure switch. Haven't followed the rear brake line yet, wanted to check the brain trust before I start pulling panels off the car.

 

Any ideas where else to look?

Do you have any wires sticking out of the wiring harness near the pedal box?

For what it's worth, it's located at the tee fitting for the rear brakes, under the diff.

What is? A Pressure switch? Not on my number 55.

Thank you! Found it after removing the 3500 screws that hold that rear under tray.

Quick trip to Autozone to find a replacement, and voila, we have working brake lights!

 

next up, possible vapor lock issue
