One thing I'd suggest that you do is pull the stereo back out of the dash and take note of it's serial numbers. Then unplug the stereo then check the wiring going to the stereo and also trace any wiring harness's wiring just in case a wire is damaged or loose or disconnected.































Go into the fuse box and check the fuse chart for any fuses that are related to the stereo system and note usually there are two fuses for the stereo.You may have blown a fuse or crossed wires causing a short that will blow a fuse or damage/melt wiring.I'd suggest that you try replacing these two fuses with the same amperage fuse.































Go over the plug in connectors that run to the stereo and make sure none are damaged/melted.Try using a 12 volt test probe, ground the negative clamped lead wire to the chassis or frame and then with the ignition in the run position and the stereo disconnected, touch the test probe's tip to each one of the wires or plug in connector pin connections one at a time.Note lightly pinch the wires or use the end that plugs into the stereo to test with.You should see the two wires that will make the test probe light up.If you don't see the test probe lighting up at all then check it by touching it to each side of the fuses bec with the key in the run position most or all the fuses should be live at each end.Note the basic Bussmann plastic fuses have a piece of metal at each end that you use the test probe tips on to test them with.































































Hope that helps and best of luck.By the way here is the Honda site that you can get the radio codes from for free. https://www.ahm-ownerlink.com/login....Fprod_home.asp















If you had to cut and splice wires in order to connect up the new stereo's wiring then it's probably a bad connection or wires that aren't spliced to the right wires or a loose or damaged wiring or a blown fuse.Note if the stereo that was in the car was a factory installed unit it may have a security code that has to be entered and that's why you want the stereo's serial numbers so you can ask dealership pr look online for the proper security codes and procedures.Otherwise the numbers or info maybe on a label in the dash or in one of the hand books.































Here is the diagram for a 2005 Civic and it's probably the same or close to your 2002.
