Brake Warning Light on Dash
Brake Warning Light on Dash is on -
Parking Brake connector is disconnected and is currently not on.
Light Stays on
When I remove proportional valve switch connector- Light goes off.
No Leaks, master cylinder is full.
How to diagnose? Any Suggestions?

If master is full, no leaks present, and brakes are as they should be, replace the prop valve switch.
