Subject: PACKARD 32 WAY CONNECTOR IDENTIFICATION


Model and Year: 1980-90 A, B, F, G, J, L, W, Y CARS AND ALL TRUCKS WITH GMP4 ECM APPLICATIONS


TO: ALL CHEVROLET DEALERS

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 connectors. To properly identify these connectors, the strain reliefs must be removed. Use the lettering on the connector as shown on figure.

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, found in the 6E and 8D Sections of the affected Service Manuals.
