i have a 91 firebird v6 3.1 ok heres my problem i had a factory radio i wanted to switch it out with a after market radio so i pulled out the old radio an i accidently cut the main harness i dont know why i did that but when i realize it i repaired the wires matched them back up and now my radio doesnt work all of the wires are correctly matched an i got a test light and tested the wires i have one power wire when the key is on im pretty sure i should have two an i checked my radio fuse it was ok any ideas??? thanks Mike
