where can i obtain a engine wiring schematic for a 1990 cherokee laredo with a automatic & AC? don't tell me the factory cause they DON'T HAVE A CLUE.

 

On my second or third trip to the library to access their online data and print it, the gal told me I could just access it at home with my library card #. It's gotten so complicated it's broken down into smaller pieces sometimes. Just the starting circuit takes nearly a page.

 

Do you have any friends that work at repair shops? If so ask said friend to get you one off mitchell or all data, that's how I got mine for my 88. Or just ask the repair shop, the worse they will say is no, lol.
