COMPLETE VEHICLE- WIRING DIAGRAMS

At the Cadillac National Service Managers' Council and at Cadillac Listening Post meetings, dealer service managers indicated that there is demand for the "bedsheet" wiring diagrams which were discontinued in 1986.

As a pilot program, Cadillac Customer Satisfaction has developed bedsheet wiring diagrams for the 1990 Eldorado and Seville. One set of diagrams is attached. Additional copies of the wiring diagrams are available and can be ordered from:

Helm, Incorporated P.O. Box 07130 Detroit, MI 48207 (313) 883-1430

Form Number: H-2716W Price: $10.00

The diagrams attached are different from the 1985 vintage in that they are not in color and that there are three diagrams to represent the increased car content from 1985.

Please forward comments about the diagram via the Service Manual Revision Request forms which can be found in the New Product Information Manuals.

It is important to note that sales through Helm will determine the future direction of this program. If demand is sufficient, similar wiring diagrams for other Cadillac carlines will be developed and made available.

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.
