Get the ground wire on the wiring cables from the stereo back, then cut some portion of the antenna wire off with a Muzata wire cutter.

Step 3

Connect the antenna wire with the black ground wire using an insulated butt connector.

If you do not have an antenna wire, you will need to get one and cut it to a reasonable length where it will be able to connect to the ground wire of the car stereo.

Step 4

After connecting the antenna wire to the ground wire, you connect your car head unit back to its original spot. Put it on, press the radio button and search for an FM frequency station.

You will get some FM frequency station on your car stereo (the head unit) because the antenna wire is now connected to the ground wire, and the ground wire connects to the car chassis, which now acts as an antenna for your car.
