I appreciate this as well Joel...

As a word of caution to future users though...
My 1990 GT seems to have a wiring harness from a 91.
The pin locations seem to be the same between 90 and 91, but some of the wire colors are different.

Here's a tip......

1. Open and save them to your computer.
2. Open them with MS Paint in your computer
3. Print them after you set the printer parameters-picture size in one page from MS Paint.
