PACKARD CONNECTOR I.D. FOR ALL ECM'S WITH 32 WAY CONNECTORS

Models Affected: 1980-89 ALL MODELS

This bulletin serves to clarify the labeling of the Packard 32 way connectors used on the GMP4 under dash ECMs.

Currently a common strain relief is used in both the C-D 32 pin and the E-F 32 pin connector. To properly identify these connectors, the strain reliefs must be removed. Use the lettering on the connector as shown on the attached document.

The colors used at this time for the 32 pin E-F connector are yellow, mint green or orange.

This updates any previous information released concerning identification that indicates any of these colors as being C & D connectors.

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.
