Note to User:
As part of our mission to provide an up-to-date website that includes detailed Body Builder
Manuals, Technical Bulletins, and Best Practice Manuals, we are now using sectional excerpts
directly from the General Motors Service Information publications for our Electrical Body
Builder Manuals.
You will note that the section numbers are non-sequential as we have provided only those that
are believed to be the most pertinent to the Upfitter community and best suited to their
needs*.
This new usage of the Service Information provides the opportunity for us to remain consistent
with the changes that take place throughout the model year and to provide you updated
information in a timelier fashion.
* If you would like to have access to all of the electrical Service
Information, please apply for a subscription from ACDelco at
