This bulletin provides LATE PRODUCTION AND DESIGN CHANGE INFORMATION ranging from wire gauge and color changes to changing connector pinout identification and wiring routing changes in Section 8A.
Please update your 1992 Eighty Eight and Ninety Eight Service Manuals accordingly.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
