Since the shop manuals and wiring diagrams are the ONLY "pork" that is not included in the stimulus package, here is a simple tip.....go to EGAY.com and find their search page and type in "shop manual" and "chevrolet" and 1990. Press ENTER. A screen will pop up with several shop manuals that are for sale.

Please dont buy the cheap Chilton or Motor manuals...they are junk and are written to be generic.... not specific for a model.
