How do you wire a radio in a 1994 Geo Metro?

To wire a radio in a 1994 Geo Metro, start by disconnecting the car battery to ensure safety. Remove the dashboard panels to access the radio, then disconnect the old radio's wiring harness and antenna. Connect the new radio's wiring harness to the car's harness, matching the colors (typically red for power, black for ground, etc.), and connect the antenna. Finally, secure the radio in place, reassemble the dashboard, and reconnect the battery to test the new radio.
