Then, connect the wires from the adapter to the corresponding wires on your new radio. Be sure to match up the wire colors correctly.
Step 4: Secure the Radio
Once all of the wires are connected, you can secure the new radio into place. Screw in the mounting bracket for the new radio and attach any additional trim pieces or faceplates as needed.
Step 5: Test the Radio
