Anybody Know?

Anybody know where I can get a COMPLETE & IN-DEPTH wiring diagram for a 1990 Olds Cutlass Ciera ,3.3L V6 FI ??????????????????????
Neither my Haynes nor Chilton manuals have enough info.
Called dealers and parts stores-------still no help!!!
I know they must exist somewhere!

I'd look in the largest library near me or swap meets, if I didn't want to spend a lot of money. If money is not an issue I'd check this: http://www.helminc.com/helm/product2.asp?class%5F2=OLD&mk=Oldsmobile&yr=1990&md=Cutlass+Ciera&dt=&module=&from=result&Style=&Sku=90OLDSA&itemtype=B&mscsid=K6F9DUXAH2TU9HTG38XFKD11CC06FC18

BTW, what are you looking for specifically. I may have access to one.

Thanks I will try the link.

What I'm looking for is a color wiring diagram specifically for that year,make,model, and engine size. I have had quite a few electrical repairs to make and would really appreciate having more info to cut back on time spent tracing back wires, testing circuits and trying to locate grounds. Also anything that can give me info on what readings are considered to be ok in certain circuits, sensors, etc. I do not have much experience in electrical diagnostics so anything that will help me would be great. I plan on keeping this car for quite a few years yet.
