        Have you checked the fuse? Do you have a plug for a trailer? If so, check those connection as well…

          It makes me nervous that you used the word pressure. Where is this switch at? If you’re talking about the pressure differential switch that’s going to be tapped into the brake plumbing, you went after the wrong switch. There is a brake light switch that you’d want to look at that’s mounted up high on the brake pedal assembly. According to the wiring diagram, you can jumper pins E and F on the connector and if the brake lights illuminate, you’ve found your problem. The diagram also says they’ll be brown and purple wires.

              Helo 🙂
              First check if you have Power to brake switch, and if you have , then check if you have out of it.
              you have a stoplamp relay in underhood fuseblock.
