2000 Jimmy Radio

Just wondering if anyone knows where i could find schematics for my 2000 Jimmy factory AM/FM CD Player by Delco? I've tried searching but can't seem to come up with anything. I am trying to find out the wiring configuration for the Aux input. Any help would be greatly appreciated!!!

There is no wiring for an aux input on the factory radio as far as I know... You need a PIE adapter, you can get them at www.crutchfield.com
