I am having electrical issues with my 88 van 20. Does anyone know where I can find wiring diagrams for it online? The radio and some interior lights aren't working right. Or the horn.

I don't know what's available online (I can never find anything when I need it). I did find the GM manual (electrical wiring and diagnosis) for my '92 G30 at www.books4cars.com for $30.
As far as your electrical issue, check the fuses with a test light to see if they are even getting juice. If not then you'll need to look for a problem with a fusible link or possibly a bad ignition switch.
