My radio seems to work intermittently. At times it will work when I start the truck,then stop making any sound. There doesn't seem to be any rime or reason to why it does this.
I found this page ( http://www.installdr.com/InstallDocs/GM/PDF/460001.pdf ) somewhere on this site. It has everything I'll need to know about installing a new radio in the dash. I have decided to replace the original radio with one from Radio Shack. They have everything I'll need to complete this project.
