PACKARD 32 WAY CONNECTOR IDENTIFICATION FOR ALL GMP4 ECM APPLICATIONS
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.
