I can think of two things that can trip the light:
1. Loose parking brake pedal.
2. Faulty brake line pressure switch.


Good luck!

I would suggest checking the brake proportioning valve, and possibly replacing it. Trace the coil lines from the master cylinder to under the lower radiator shroud to it. I went to the salvage and got another one and now mine does not come on.
