That's right but not for 83.5 as the brake fluid level switch was added
to the fluid reservoir starting in 1985 models. Before that the light
was connected to the dual pressure switches on the master cylinder and
was meant to detect when one side of the cylinder had lost pressure
compared to the other. That pressure feature was removed when the fluid
level switch was added but he has it in his 83.5.
