Ken,
Thanks for your input. The GMC Assembly Manual does show some electrical wiring ground points. However because I have only the scanned downloaded version it is not searchable nor very clear... not that the paper version is searchable either.

However we are only dealing with low current DC grounds. When troubleshooting and find that a bad ground is the cause of a problem, in most cases another wire can be spliced in and grounded to a convenient point. Note this is only true for low current items like lighting etc. High current items such as the main battery ground must go to the engine block.
