That switch switches between the original pressure sensor and the after market sensor that tricks the system into thinking it at original pressure when in reality it’s about 20 psi higher. No programming required.

Are referring to the my picture with the high low sticker I made?

The switch is circled in red on the schematic.

Found the thread look on page 15 of the thread.

I installed this switch 8 months ago on a different thread.
