Where do you find a wiring diagram for 1999 civic stereo?
If you are looking for the routing of the wiring for the speakers, you will have dificulty finding one. A wiring harnes connects to the back of the stereo and it would be wise to purchase an installation trim kit that come with a wiring harness to match your new stereo to that of the car.
The wiring harness from the 1999 stereo has a 21 prong plug and the 1995 has a 14 prong plug you can purshase a harness from Honda but it has to be hadrwired to the exsisting wiring but don't screw it up, go to Honda and get a wiring diagram for the both of them to match up the wiring you need to make it work.
I bought a kit from all places, Wal-Mart. Turns out I bought the plastic parts thinking it had the wiring along with it but it didn't. But what it did have was the wiring diagram and I was able to match our 1999 Avalon with the wiring with the new stereo. With lots of thread baring and joining together, it works perfectly. Later at Wal-Mart, they do have the wiring kit that would have made…
Go to your local parts store and ask them for a Haynes repair manual for the year and type of your vehicle. It costs around $17.00, and although it is not the best, there is enough info in there to get your stereo wiring figured out. Chiltons also makes manuals, plus there is always the dealer. Sometimes even the dealer will print out a page of schematics for you. It just depends on their generosity.
