Hook it up with the red wire from new radio. There should be a black ground wire as well from the "chime box"

its already wired into the harness. the only loose wire is the red one

I figured I could splice it and tie it in but I didn't want to burn something up


The red wire from the chime box gets joined to the red wire from the radio. You might have 3 red wires hooked together its ok. Make sure the blue/w white stripe wires are hooked up as well. They are for the factory amp remote turn on.

Blue w/white stripe from the radio to the blue w/white stripe from the wiring harness. They will be marked: amp remote, amp turn on, amplifier, the one on the radio might even say power ant. (antenna).
