  1. Chetan, save yourself the trouble of trying to figure out what wire go where and purchase a OEM stereo wire harness. This OEM stereo wire harness is the exact same plugs that plug into the stock radio. Here is the wiring harness you need:

    Hope this helps. Good luck with your radio wire harness replacement.

  2. Hi, i have lost the harness. would it be possible for you to call out the connections with the pin numbers like you have called it out for the color codes?

    thanks!

  3. you guys are completly awesome!!! how do i make a donation to the website i never want to have to do another radio install without you guys

  4. Thanks Guys,
    I bought a 1999 Civic Si for my daughter and had to replace the stereo after a local garage caused a 2 amp draw to be constantly applied on the direct battery wire. Your wiring information was just what I needed to complete the installation job. Now if I could only find a manual for the after market car alarm that came with the car!

  5. Thank you so much guys! Websites like this works wonders! Now I can stop second guessing my work and not have to pay big bucks for the pro’s to do it.
