Electrical Problem
 

I have a 1988 C1500 Chevy truck with 305 motor. my radio wasn't wired right by the previous owner so I took it out. I think it was wired to the ignition. does anyone know how these wires can easily be hooked up to make the truck run? if I hook them up wrong the lights on the dash stay on and when the key is turned off the truck continues to run.
