I have a 2000 silverado factory cd I'm sellin and need to double check that all the lights work and just need to find the radio illumination pin on the back so I can bench test it. I know the rest works fine and really don't want to go through the hassle of takin my aftrmkt radio out just to plug this in to test. i have searched but cannot find a diagram for the back of the radio to see which pin is for illumination. any help is greatly appreciated

 

I think this diagram will work for you. The two pins you need are next to each other. There are two connectors laid out opposite from each other (4 pins on left, or 4 pins on right). Look at the back of the radio to determine where THIS connector would fit:

Glad to hear it worked for you!
