I have a 2000 VW Passat GLS that I'm trying to install a Dual stereo system into but I can't figure out what the wire colors on the car are for each thing (power, ground, etc.). I've looked online through...


First of all I would highly reccommend you use a wiring harness such as the Metra 70-1784 or the Scosche VW01B for two reasons; 1) it will make things 10 times easier for you and 2) it will keep all your factory wiring intact.

If you want to tackle this without using a wire harness do not just go and cut off your factory plugs, leave them on in case you ever need to change out the radio to a different model/brand of if you ever decide to sell the car or trade it in you can put your factory radio back in and keep your nice new radio for the new car. Just tap into the wires behind the plugs and make sure to insulate your connections really well so you don't pop fuses or worse.

Here's the wire colors and what they do:

12 volt constant wire - Red/blue
Ground wire - Brown
Radio ignition wire - Red (thicker red wire)
Radio illumination wire - Gray/blue

Front left speaker - Red/green (+) and Brown/green (-)
Front right speaker - Red (+) and Brown/red (-)
Rear left speaker - Blue/white (+) and Brown/white (-)
Rear right speaker - Blue (+) and Brown/blue (-)

If you're using a amplified antenna adapter that has a blue wire attached to it, connect that blue wire to the thicker red radio ignition wire.

Hope that helps.

It won't connect to my 98 dodge ram. I order a wiring harness for my dodge but what i got is already in my truck


There are scosche, aftermarket to factory wiring harness at Wal-marts for about $10-15.
Or you could hard wire, the stereo harness into the factory directly. It is not very hard to do. If remember right, there was no good factory ground, so you would have to run one yourself. As with any electronics installation a multimeter or test light can be useful, but a good wire striping tool and electrical tape will be needed.
I would start by checking my factory harness with the multi-meter, and finding (or rechecking for) the wire with 12v that is constantly on, and for the wire with 12v only when the ignition key is turned to either "on" or "Accessory". The wire colors for your truck, should be:
Constant 12V+ Red
Switched 12V+ Red/White
Dimmer Orange/White
Antenna Trigger Yellow
Left Front (+) Dark Green
Left Front (-) Brown/Red
Right Front (+) Purple
Right Front (-) Dark Blue/Red
Left Rear (+) Brown/Yellow
Left Rear (-) Brown/Light Blue
Right Rear (+) Dark Blue/White
Right Rear (-) Dark Blue/Orange

Now that is the basic factory package, if you have an upgraded model with a factory amp (not very common) it will be different, but same concept applies.

Scosche FIA-3A Tie into rear spekers of a 300C to power a sub amp


Hello herg1076,
Here's a link to www.modifiedlife.com which will have a page showing the color codes for your vehicle wiring. The 2008 Chrysler 300 rear speakers are shown as follows: Left positive is Dark Green/Tan, Left negative is Dark Green/Gray, Right positive is Dark Green/Brown, and Right negative is Yellow/Green. Other models and other years will be different, so be sure that you browse to the correct color codes for your specific vehicle.
Hope this helps.

1995 stony creek popup by fleetwood/coleman I need to know whateach of the colored wires in the six prong trailer plug go to


Hi Sk,
Horse, stock or utility trailers:

White = Ground - GD
Yellow = Left turn/Brake -LT
Green = Right turn Brake -RT
Brown = Tail and clearance lights - TM
Red or Black (not both) = Battery, aux power - A
Blue = Electric Brakes - S

Recreational Vehicle: (color, use, plug mark)
White = Ground - GD
Yellow = Not used -
Brown = Right turn Brake - RT
Green = Tail and clearance lights -TM
Black = Battery, aux power - A
Red = Left turn/Brake - LT
Blue = Electric Brakes - S


Ground should be 10ga.
Others 14 ga

That ought to do it,
Mike
