Well i ordered a Sony CTX-GT340. I also ordered the wiring harness to fit into my 1984 Nissan 200sx. Well i plugged in all the wires to the harness, and i have two green and two pruple and a orange that are just sitting around. when i flip on the radio it runs on, but doesnt play music. Neither cd or raido work. Then it says that there is a malfunction with the speaker wires. im thinking this is the green and purple, but it doesnt have a place to go. Please help
