Re: Help w/ RPO on E/C Sequence Sheet

The red pencil may mean something. Keith Seymore would be the guy to ask since he worked in the assembly plants. Maybe he'll pipe up.

There are RPO definitions in some of the parts books. Look in the manuals link in my signature for download links to the parts books.

RTFM... GM Parts Books, GM Schematics, GM service manuals, and GM training materials...Please include at least the year and model in your threads. It'll be easier to answer your questions.
And please let us know if and how your repairs were successful.
