Hey folks, I recently purchased a 1993 K/1500 4x4 5.7L. This is the first Chevy that I've ever owned. The radio wasn't working when I bought it, but I found a bad fuse for the courtesy lights and the radio started powering on when I replaced the light fuse.

I'm not getting much of a signal on the antenna though. I found that the radio on the dash is just a "dummy" box and that the tuner & control is under the dash near the gas pedal, but I can't find where the antenna hooks up. Any ideas?

Thanks in advance!
