black is ground
red is +12 volt (switched)
yellow is +12 always on
These are common and should match the colors on your current harness. Check with a multimeter to be sure.
I am not sure about the green...
I purchased an In-Dash LCD Monitor (composite video) for my 2000 VW Passat. Its just the monitor, with no stereo reciever/cd player or anything. I want to hook it up to the empty din slot I have below my radio. I am going to keep my radio, and was wondering if it would be safe to connect the monitor, to the same power harness for the radio? If so, how can I hook this Monitor up? Unfortunately, the little booklet that came with this monitor does not help. The wiring on the back of the monitor has 1 Black, 1 Red, 1 Yellow and 1 Green wire. I'm just not sure what color wires I would pigtail each to in the harness that connects to the radio. Also, would I need any additional fuses or anything? The yellow wire on the back of the monitor already has an inline fuse built in. Anything else I should know? Thanks!

Yes, you should search... and Yes, It has been covered before!

Here is a picture of my radio power harness wiring diagram:
According to this, I should wire the black wire from the back of the LCD monitor to the Thick Tan Wire (P) on my radio harness. Then the yellow wire from the LCD to the Thick Red Wire With White Stripe (O). And the Red wire from the LCD to the Yellow with Red Stripe Wire on the radio harness. Does this seem correct? I believe the Green wire is the safety parking wire, so that the monitor could only be used when parked. Should I just leave this alone, or should I ground it to the Thick Tan wire aka The ground wire (P) on my radio harness?
Do I need to connect any fuses or anything?
Dude, do you even know what you're doing?
To tell you the truth, I wouldn't wire it to your radio's harness. Why not just run new wires? It would be a shame if anything went wrong.
Quite possibly you would need to ground the green wire, where did you buy this monitor?
Why don't you bench test with it before you install.
You have to follow the little booklet to determine what is power and what is ground, and what the other wires are. THERE IS NO STANDARD FOR WIRE COLORS, as the wiring diagram for your stereo clearly points out.
Sure, there is a "convention" of sorts, Red is positive, black is negative, but like I said, there is no rule or standard.
Now really, this appears to be too much for you to do. I would consider having a professional do it for you.
As for hooking it to your stereo harness, you will probably have no problems, cause MOST monitors use less then an amp of power, but no gurantees. Running your own wires is always the BEST and SAFEST bet.

Alright hold up fellas... This is the newbie forum, so obviously I don't know fully what I'm doing. Thats why I'm asking. I wanna try to do this myself, without having to go to a professional installer. The little booklet is horrible. It only has 1 page that barely touches on the powering of the unit. It doesn't refer specifically to the wires. It shows red and black, but I don't know if it is referring to the battery terminal color or the actual wires themselves. If so, it makes no mention of the yellow wire and the green wire. Here is a scan of it:

Well, that diagram CLEARLY shows the red wire going to "+" on the battery, and the black wire going to the "-" of the battery. While I understand that you are posting in the newbie section, understanding positive and negative should be a given, and not something that needs to be taught.
Unfortunately, since the manual doesn't say, NO ONE HERE CAN TELL YOU HOW TO HOOK UP the yellow and green. Sure, I can tell you, Ground the green, and power the yellow, but that could be totally wrong, and then your screen will emit the magic white smoke.
Call the seller/manufacturer, or go to thier website, and see what they say.
Like I said before, there is no STANDARD wiring color.

P.S. Actually, after reading your post that says that the Yellow has a fuse, what about the red wire. Now I am begining to think that the "manual" you have is bad as well. If the red goes to positive, as the manual says, then it should have a fuse as well/instead. DAMN CHINESE MANUFACTURERS. This is what happens when you got the ebay/cheap as hell route, from an unknown vendor. Good luck with getting any information or support.

Actually the diagram doesnt show the red wire going to the "+" and the black wire going to the "-". It looks more like it is referring to the red and black on the battery terminal, as opposed to those specific colored wires. Take a better look. TruckinMP3's seems to have a better understanding of what I'm trying to get. Unfortunately, since this is one of those cheapo EBAY Hong Kong units, there is no manufacturing company number to be found. The brand is Avatar. Heck, the EBAY seller who sold this item, cant even be found anymore. I was hoping someone who purchased a similar in-dash monitor from EBAY, would have the know how.
I know it is really small, but....don't you see, in the little circles just above the word "battery" that has a little "+" and "-" sign??

How'd you come out on this man? Can you take pictures of it?
