Radio hook-up problems

Did you figure it out? In situations like this I like to have a wiring diagram to figure out which wire is which.

i had the same problem check the horn fuse its the constant power wire for the radio dont ask y just a gm thing

make sure you have a good ground you may have to run your own wire

Check the fuse. I did this hooking up subs and an amp with my new radio. If the wires make contact with bare metal then it will blow the fuse.This is probably what is wrong.
