Step 1

So starting this guide for How to Connect Car Stereo Wires.  First of all, you have to buy the wiring harness from the market so that you can attach to your car’s new stereo. If you have bought it already with your new stereo than well done, also keep the other things with you while starting this work like tools, e.g screwdrivers, wire cutters etc and the connectors to connect the wires firmly

Connect each and every single colored wire of the wiring harness with the stereo same color wires properly.

Step 3

After making the connections of the wires, make sure that those connections are strong enough if you don’t use connectors than you can do wire crimping and too strong this connection you can apply any tape on it but it is still not the best option. Another option for my dear reader is that you can easily connect these wires by soldering because it is still secured than the crimping method.

Soldering is basically a method which uses a metal that can be melted and is applied over both connected wires and then it gets dried up and makes a strong connection of the wires.

Personally, I like to use the connectors for the wires connected as it does not make so much time, it’s easy to connect the wires with these connectors and also it ensures the strong connection so why not to choose this convenient, strong and easy method.

If you find any kind of difficulty in the connection, use the tools whose names I have told above like use the wire cutter and trim the wires, a little bit so that it can easily come in the grip of the connector and it is pretty much simple to do.

Whichever the method you found the best convenient, go for it but it is just that the connection should be powerful and stable

So must ensure to ground your stereo by connecting it with this earth wire properly. After that, you will be all done. All the wires connections are done by ensured strong connection

Step 5

After that, it is a must that you should check out that if the stereo connection is working or not. So check the connections by using the continuity test using the voltmeter. Set the voltmeter. Connect the two weeds of the voltmeter and if they make a beam sound than well done you have ensured testing for the right connections. You can also test the good connection by directly placing the one probe back into the harness and one on the other side of the harness and double check it by hearing the beam sound

Step 6
