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