Yes, the wiring at the parking brake lever as well as the flimsy switch
there are the more likely cause. It is just a single "ground" wire,
grounded to the chassis through the switch. The switch is just a cheesy
thing identical to the front door interior light switchs in the door
frame. If the flimsy switch is bent, just leaning your hand on one side
or the other of the parking brake handle may make the light flash on/off
The fluid level circuit and wiring is part of the dash wiring harness
and switching instrument clusters does not affect it. You can tell if
your vehicle has the brake fluid level sensor quite easily. In the top
side of the fluid reservoir cap is a 2 pin connector and 2 wires plug in
there. The level float switch is part of the newer type cap. There is a
round plastic float/rod sticking down into the fluid from the newer caps
When there is enough fluid, the float pushes up and opens a switch
inside the cap. The older cap is just a plain cap, nothing sticking down
and no connector out the top.
The parts data shows Canadian models changing over to the newer circuit
at the same time as US models, 1985 model year.
