This new bulkhead connector uses all the same circuits and wire colors as all the other "1983" LeSabres and Regals. The only difference is the actual connector itself; therefore, the engine, forward lamp and instrument panel harnesses will not be interchangeable with existing harnesses. (See Figure 1) When diagnosing electrical conditions, use the 1983 Buick Service Manual and Figure 2 showing pin cavity locations in the new connector.

If it becomes necessary to replace either the engine harness, forward lamp harness or instrument panel harness on vehicles equipped with the new bulkhead connector, use the following part numbers. Vehicles not equipped with the new connector will use the part numbers listed in the parts book.

LeSabres Regals

*Instrument Panel 12036345 *Instrument Panel 12036346 Engine 12035228 Engine 12035231 Forward Lamp 12035229 Forward Lamp 12035232

*These part numbers are less the remote lamp driver module. If you also wish to receive the module, order part number 12020004, along with the appropriate harness number.

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.
