About 6 years ago my stepfather decided to install a new radio for my mom in her late model 95 Camaro. Well somehow he f'ed it up. The interior lights haven't worked since he did it and neither has the trunk button. I got the car a couple weeks back and decided i wanted to fix this little problem so I took the radio and looked at the harness and it is one messed up job. Honestly I don't understand how its so hard to hook up a stereo but apparently he just didn't understand it. Theres 2 wires that aren't stock running from the fuse box under the dash and into the wiring harness. When the yellow one isn't hooked up the horn and cigarette lighter dont work. We managed to get the interior lights to work but it keeps blowing fuses. And when the wires for the horn and the interior lights are hooked up the car idles high for about 2 seconds when you start it but doesn't do it when they aren't hooked up...does anyone have a wiring diagram? Some pics of their stereo harness maybe? Honestly I dont know what he's done but it has me stumped. Any insight into this would be great. I'll post some pics when I tear back into it.
