I bought a 2005 RCBS 2wd 4.8 5 speed silverado that only came with a factory am/fm radio with no cd or cassette. I bought a factory single cd player from a 2004 silverado. Once I installed the cd player it shows it is locked so there is no way yet for me to tell if it will work. I noticed the am/fm radio I removed from the truck had 1 port to plug in wires and the cd player had 2 ports to plug in wires. I pluged in the connector to the cd player that was plugged into the radio but it has the other port that my am/fm radio never had. What is this for and do I need another wire to plug in for the cd player to work or once I get it unlocked will it work like it should the way it is? THANKS!
