What Do Electrical Wire Color Codes Mean? ' Angies List

I hope someone comes along who can help; in the meantime, you might try the following. Naturally the power wires will be 12V and usually red(+) and black(-), if they're not, you can examine the other colors, to determine if their are separate ground wires for each speaker. If it uses a remote, and you want to hook that up; I can't help. sorry. But, if the speakers have a common ground, there will only be 1 wire for each speaker, the other connects to the ground of the car. If there are two wires for each speaker, they will be 4 different colors, with a 2nd wire which has the same color for all 4 speakers, so each speaker has a colored wire, and a common colored wire. This will leave the power connections, unless you have other controllers (see above).

One you know which are the power wires, you can connect them to a spare 12 V battery, and then comes the fun part. While adjusting the radio for front back, left and right, using the colored and a common wire for each speaker, this will be the same as the ground wire for the power even if not the same color, you can connect it to ground for the test. Then connect the colored wire and common wire to a speaker, by adjusting the controls you can find out if that colored wire is for front or back, left or right. Then you'll have your color code.

Although prolonged use of only one speaker or only two could cause damage to the radio, short use to troubleshoot at low volume shouldn't be an issue. Just don't use it that way.for a long time!

I hope this helps. Let me know.by rating up my answer! :-)

Okay, you know each injector has a power wire, and a ground wire that goes into the pcm? All of the power wires to all six injectors is a green wire with a red stripe.

The ground wire colors are as follows:
inj 1: green wire/blue stripe.
Inj 2: gray wire/yellow stripe
Inj 3: violet wire/gray stripe
Inj 4: yellow wire/orange stripe
Inj 5: brown wire
Inj 6: green wire/white stripe

I should note that the wiring diagram I am looking at shows this diagram as from a 2008 model manufactured during 2nd quarter of the year 2008. If your injector wire colors are different than as listed above, there may have been production changes during the year. But the power wires to all six injectors would still have the same color wire. You could figure it out that way: in other words, looking at the injector harness, same wire color to all six is the power wire, all the odd colors are the ground wire for that injector. Hope this makes sense to you. Good luck.

red for battery power
orange for ignition power
black for ground
those are basic wiring power,, the rest of wire are for speakers and equipment like rda

Locate the wires running off from the O2 sensor. There should be two. The black wire is the ground wire. The other wire, which may vary in color, supplies power to the sensor.

2 Connect the power lead to the corresponding connector on the chassis's wiring harness.

3 Connect the black, or ground, lead to the corresponding connector on the factory wiring harness.

3 wires, "how do i wire it" are simply explained. all universal 3 wire o2 sensors will have 2 wires one color, the other wire a different color. the 2 that are the same color are ground and power for the heater and it doens't matter which one is which. so ground to the motor, power from the gray wire on the fuel pump, or anywhere you want to pull 12 volts while the car is running. i have a dedicated fan relay that doesn't use the ecm and runs off the key, so thats where i went. the different color wire goes to the stock sensor wire, it's the signal.

power up the power supply an use a multi-meter to measure the voltage between the black wires and the other colored wires to determine the voltage on each of the colored wires.

Well colors can vary, but basically bare copper or green are grounds, white is the neutral wire (but it is powered in a switch loop, and when used in a switch loop it is taped with a piece of electrical tape to show it is powered). Black, red, blue, brown, and pretty much any other color except green and white can be a power wire (black red and blue are the most common colors used).

The power color is red,the negative lead is black,the constant power is yellow.Now for the speakers ,the white lead is the + and the white with the black line on it is the - wire ,grey wire + and grey with black line wire - ,green wire + and green wire with black line wire -,purple wire + and purple with black line -.Hope that clear your mind.

black is usually power and if there is a blue its the feedback to the pcm
