    What is the purpose of the instrument panel wiring harness module? What are the symptoms if this unit is bad? Is it part of the electronic brake control module?

      I'm happy to help, The Weekender! BWD calls this a Brake Indicator Lamp Module (Part No. GPL100). It is part of the electronic brake control module system. This part controls the illumination of the ABS light on the dash. The most noticeable symptom of its failure would be the ABS lamp does not illuminating when starting the vehicle.

      A repair manual for your 1993 Buick LeSabre 3.8L V6, such as Haynes Part No. 19020 or Chilton Part No. 28200, may provide diagnostic procedures. If you require additional diagnostic assistance, I suggest consulting with a certified mechanic.
