If you have jumpered both sensors at the same time and the light is still
on, then the problem is upstream and a nightmare to find...  Here is the
Dave Head "We don't need no stinking idiot lights" trick:

You have to remove the Auto-Check main control unit - to the center of the
car and above the glove box under the dash. Once out, there is a 35 pin
connector to it.  One end has a fork end. Counting from the other end (latch
end) - 1-18 on top, 19-35 on bottom. Bottom shound be smooth. Jumper from
pin 21 (sensor) to pin 27 (ground - always brown). This will put the light
out. Good fix for all 85-88 5KS, 5Kt, 5Kq, 5Ktq. Bentley pages 96.28 and
96.29 refers.

Book tells you to go through the console AC controller to get to it. I found
it much easier to access via the glove box removal method. This method
simply inserts a signal that tells the Auto Check that the circuit is
complete. Remember to check your brake pads often and put a note in the
glovebox for any future owner...
