Ok heres the issue, I let some friends help put my amp and new cd player in, i put cd player in tested it it worked great, ten they ran rca and remote wires and hooked up system. I went to turn on radio and when i turned key to acc the 4x4 and low gear light was on and that pump and the inner fender behind pass batt was buzzing away for like 2 min, and radio wont work. i knew i should have done it myself

but hey the "knew what they were doing" please help its supposed to be my work truck. the truck does still start
