Silly me. I went looking in the electrical manuals for this one. found it instead in the engine manual. over the years, I've worked on ford, chrysler, VW, fiat, bmw and volvo. I have never had such problems with finding what I need in the shop manual as on this saturn. Not that the manual itself is bad, just finding what you need is hard. It's just one of those things which works best online where you can search for any term and find all the occurrences.
