car radio

Quick answer: Got to Wal*Mart. Go to the car stereo section. Look for the wiring adapters, and get the one that says Toyota. Match the wires from your new stereo to the wires on the harness (the colors should match. CHECK the manual from the stereo to the color code on the back of the harness package). Cover connections with electrical tape.

Match the connector from your car with the new harness adapter. Plug them together. Install the radio in the dash. Replace the trim. Turn it on.

Hopefully, you posted your question before you cut any wires in the car...
