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

 

 

yea i fixed the wires an plugged in the old radio an it doesnt work

 

 

yea yellow has power but the orange doesnt an the display doesnt light up but it worked before i took it out of my truck and the factory radio doesnt light up either

 

go back to your main jumper spot where all your constant power conections are i think its under dash drivers mounted by the hood release but high up (includes removing underdash panels and side kick panel) it should look like a mess of orange wires like seriously a mess of wires then try to trace the wire for your radio

 

If the (orange) memory wire dosent have power the radio won't work. Has to have both power wires. If you can't trace the problem you can splice into another wire that has constant power.

 

i would make shure that you dont have a melted wire or somthing weird though taping another will get your radio to work dont ignore the other wire going blank
