I have a 2000 Chevy Blazer with every package at the time the car was made. I replaced the heater core and didn't lable the wires. What does it look like, I had a black one plugged in (Im stupid and didnt lable to wires, after I replaced the heater core) but this mechanic said it was to go to the back of the radio, I had only one wire plugged in, I guess theres suppose to be two? there was a white wire I thought went to it, but it never would fit, so I said screw it, and had a long black wire going to the tape player, so now I have nothing plugged into the tape and I miss my iPod!!!!! So I'm going to try and ask you guys for help, Pictures are amazing, I just don't have camera besides my Blackberry, and it SUCKS! Sorry guys, thanks for everything any ideas help thoughts pictures. Thanks!
