Made a goof today installing a new radio. The car already had a after market radio. I took everything out and connected the power/ground/etc. Then the "goof" happened. The previous owner had a set of 4 RCAs' running out from 5 wires connected to the car. Instead of me simply connecting those RCAs' to the new head unit. I took out the RCAs', don't ask me why.

Now I am left with 5 wires that I cannot for the life of me figure out the combo needed to get the speakers working? Any help guys? Car is a 1998 with Bose system.

 

Since it has been so long I'm wondering if you have gotten this fixed already? Otherwise I can help.

 

its hard to explain but test them with a mulitmetor
