Is there anything that has the circuit/schematic for the dash "brake" light?
@Bert, it's the dash light. I bypassed the ebrake switch, checked the fluid on the reservoir and bypassed the level sensor on the reservoir, the light still stays on. I figured I'd stop looking for a needle in a haystack and get a wiring manual. By bypassed, I mean I took my DMM, found whether the sensor needed to be closed or open and simulated the off condition of that sensor.

I'm not sure what the 0v(***) means and I believe the parallel lines mean it is a power wire, while the perpendicular lines mean it is a ground wire under normal operating conditions?
I'm getting full alternator voltage at the brake fluid level indicator switch and I'm getting only 2v at the parking brake level switch when the brake is fully disengaged.
That looks like my issue as the diode segments the two circuits. But I gave the parking brake wire 14v through a 1k resistor and the lights still stayed on, which is confusing me. Based on the circuit, that should have turned it off?
