How do you check the wiring on a car stereo?
After you have marked that wire and set it aside, turn the ignition switch on, turn the headlights on, and turn the dimmer switch – if equipped – all the way up. If you find two more wires that show approximately 12V, then turn the dimmer switch down and check again. The wire that shows less than 12V at that point is the dimmer/illumination wire.
Where to place the remote turn on wire?
With the ignition in the OFF position, place the positive lead of the multimeter on the end of the remote turn on wire and place the negative lead of the multimeter to a grounding point. Be sure the positive lead is touching the wire strands inside the jacket of the remote turn on wire.
How do you check for continuity in a car stereo?
You just have to connect the ohmmeter to a known good ground and then check each of the wires in the car stereo harness for continuity. The one that shows continuity is your ground, and you can move on. You can also check for the ground wire with a test light, although it’s a better idea to use an ohmmeter if you have one.

Can a head unit have no remote wire?
A relatively common problem is installing an amplifier with a factory head unit or other head unit without a remote turn on wire (or a burned out circuit). So the amplifier doesn’t stay on 24 hours a day you need a way to turn it on and off remotely. Hence the term “remote turn on wire”.
What kind of wire do I need for a remote radio?
It’s important to use the right wire for your amplifier and other electronic equipment. In the case of both remote and antenna wires the power antenna wire will only output 12 volts when the radio is on.
Which is the correct color for a car stereo wire?
Use an inexpensive multimeter to identify wires. If you don’t have a multimeter, use a test light. Typical wire colors are yellow – 12V, orange with (/out) white stripe – dimmer, red – accessory, black – ground.
How is the polarity reversed on a car stereo?
If the cone appears to move inward, then you have the polarity reversed. If the wires aren’t in matched sets, then you simply have to choose one, connect it to one terminal of your AA battery, and touch each of the remaining wires to the positive terminal in turn. This is a longer process, but it works just the same.
