I need a radio wiring diagram for a Holden Commodore LS 1991


Regardless of colour coding, please follow the following instructions (require multimeter):


Note: Attach multimeter earth wire (black) to the vehicle body. Convenient places may be the metal ignition barrel, the vehicle's car arial plug, cigarette socket body etc.


1) Testing for voltage with key out of the ignition, locate the permanent positive wire. This will wire into the yellow wire on your new stereo. The yellow wire circuit powers the stereo's memory.


2) Testing for voltage again. This time you are testing for a wire which only offers power with the ignition turned on. This one will wire into the red wire on your new stereo, and will power the unit only with the ignition on.


3) Now you know which your vehicle's positive wires are you can now test for an earth wire. Switch the multimeter to the resistance setting. There is one setting which will allow a buzzer to sound once you find continuity. With the ignition off test each wire until you get a buzz and a low resistance reading. This should be your earth wire. Double check this with the ignition in the on position. It should remain the same. If it changes to a positive with the ignition on and with the vehicle's lights switched on, then this is the dimmer feed for the stereo's screen. If you unintentionally found the dimmer feed, then you can ignore this wire, and search again for a wire which only offers an earth.


Now you have your power and earth wires located and can wire these into your stereo before continuing.


4) Next you need to use the stereo's balance and fade controls to allow only one speaker output to work from the stereo. So let's start with Left Front speaker output only. turn the stereo volume to mid way so that you can hear when you have connected to the right speaker. bare the remaining wires on the car side and test combinations of the remaining wires until you find the front left speaker of the car. Wire your stereo's wires once you find the correct connections.


5) Repeat the above steps with all remaining wires, remembering to adjust your stereo's balance and fade controls to only allow one speaker output at a time, to ensure the only one possible channel to work and help you identify which of the car's wires power the speaker you have selected.


Before re-assembly of the dash panel, check that your stereo and all functions work properly, being sure to use your fade and balance controls again to test all speakers individually.


If you want to be extra careful and wire the vehicle's speakers positive and negative, according to your stereo's outputs, not that this makes much difference on standard stereo arrangements, then follow this next step:


Make sure you can see the speakers themselves and connect a 1.5 volt AA or AAA battery to the speaker wires. If the speaker's cone pushes forwards, then the wire you connected to the battery's + terminal is indeed the positive wire and should be wired as such. If the speaker does the reverse, then you have the wires the wrong way around. Do not repeat this test for extended periods as damage may be caused to the speaker circuit.


Tip: Always solder all connections and insulate well from each other. Stereo connections can corrode over time and are prone to movement behind the dash. Poor connections may cause faults and low quality sound.

I need the wiring diagram of the stereo cassette radio am/fm, please help my radio is dead (positive and speakers terminals)


You're going to need a multimeter/voltmeter and a 9v battery to do this. It's easiest to first find your constant and switched/ignition wires.

For the constant, you can get ground from any piece of metal inside the dash, and begin touching all the wires, one at a time until you get a voltage. The meter should show 12v or just under. This is your constant. Do the same for the ignition/switched, but this time with the ignition on. Check the remaining wires until you get one at 12v or just under. To check now turn off ignition and the voltage should go away.

For the speakers, it's a little more guessing, but you can check them with a 9v battery. Start with any of the remaining wires and hold it on the positive terminal of your 9v battery. Now go through the remaining wires and touch them, one at a time, to the negative terminal. You should hear a pop from the speaker when you come across the pair. Note the colors and the speaker where it came from. Now move on to another wire and repeat.

You may come across a wire that will not pop when paired with any of the other wires. This could be your ground. Put it a side until you've figured out all the speaker wires. Now go back to the possible ground and use your multimeter to see if you get 12v with your constant wire on positive and the negative wire on the possible ground. If it does it's your ground. If not, it could be something like a dimmer, power antenna or remote line that isn't necessary in replacing a stereo.

The downfall of doing this is that it doesn't tell you polarity. After you finishing connecting the radio to the in-dash wiring turn it on. Listen to the sound carefully. If it sounds tinny one or more of the speakers polarity are incorrect. Try to determine which speaker/s sound tinny and reverse there wiring. Check again and hopefully everything's sounding good.

I hope this is helpful.

Starter activates when battery wire connected and starter is grounded to frame with or without solenoid wire connected. No short between posts on new starter. Only does it when the power source is from the...


sounds like you are hooking up the starter wrong. the positive goes to the starter main terminal from the battery. the ignition wire goes to the s on the solenoid, which activates 12 volts when the ignition switch is turned on which causes a magnetic field
inside the solenoid and joins the connectors
in the solenoid to the main positive wire from the
battery to the main starter unit brushes/armature inside the starter unit. If you have a constant
12 volts from the ignition wire it will keep the solenoid engaged. If you put the main positive wire on the wrong solenoid terminal it will immediately engage the starter. try putting the main battery wire to the correct terminal or perhaps check the ignition wire for a short or constant voltage to the solenoid.

I need wiring color coding 4 pioneer deh 2050mpg? i know red is constant power.


Not to question you about the red being constant power but I have a pioneer deh-1600 car stereo and red is hooked to electric terminal controlled by ignition switch (on/off) and if your unit has a yellow wire that goes to constant power. The only problem with hooking up the red wire to constant would be if you happened to accidentally leave your player on it could drain the battery. Hope this helped a little. Good luck.

After replacing my battery i have to put the code in every time i start the car for the radio is this electrial or fuse problem


ok , as you may know, your car has a security feature that disables the stereo every time the power is disconnected from it. so that is your problem. you have 2 power supplies to your stereo. one is a wire that is connected to your ignition switch, so that is like an electrical switch so to say, that powers up the unit when you start the car. the second is a slightly larger wire that supplies a constant current to the stereo, even when the cars off. this wire allows the stereo to save your sound and radio presets, and other memory when you turn the ignition off. this constant wire is most likely your problem. im not sure where this wire is spliced into your battery. it may be at athe battery, or it may be a wire leading into your under hood fusebox. check the owners manual for the fuse locations, and check to see if they are bad. then, check to make sure there werent any wires or connecters that may have been left off by accident when the stereo was disconnected. finally if that doesnt work, you can locate this wire, and replace it, if you know how to use a digital multimeter. just determine what wire is the constant, cut and splice a new wire into the stereo-end of the old constant, then run that wire to a constant power supply, like directly to the positive battery post. if you do though, just make sure that the wire will be clear from any moving or hot parts, and dont forget to install some kind of fuse near the battery. im guessing a 10 amp fuse should be sufficient. hope this helps you, or at least gives you a good starting point.
