Hello. The brake pressure switch is behind the panel that is behind the brake and clutch pedals. You will probably find a few pressure switches back there. The one that your looking for is the largest one. The body is much wider than the others.

It's hard to tell from the picture. But it looks like the second from the right. Can you take a closer picture of that sensor? Is there a label on the wires?

I'm almost certain it's the second from the right. Send me your VIN and I may be able to verify with a parts breakdown picture.
