2000 Grand Prix Headunit Help

[JaceHouse]

I was just wonder if anyone had a wiring diagram for a 2000 Grand Prix or a way to test what wires are the front left +, front left -, front right +, etc.. Every diagram I've seen so far has the wiring with colors like yellow and dark/light green, but the colors don't match up on my car at all. I would post pictures of what I have in my car, but this website won't let me.

Anyway, if you guys could give any insight on what wires would be what or how to find out what wire is what, that would be great. Thanks in advance!

What the diagrams I see have the colors as:

Constant 12V+ Orange

Switched 12V+ Yellow

Ground Black

Illumination Brown

Dimmer Gray

Front Speakers 5 1/4" Doors

Left Front (+) Tan

Left Front (-) Gray

Right Front (+) Light Green

Right Front (-) Dark Green

Rear Speakers 6" x 9" Rear Deck

Left Rear (+) Brown

Left Rear (-) Yellow

Right Rear (+) Dark Blue

Right Rear (-) Light Blue

The only colors I have figured out so far

What the diagrams I see have the colors as:

Constant 12V+ Orange

Switched 12V+ Yellow

Ground Black/White

The adapter I have looks like this:

xxxx xxxxxx

xxxxxx xxxx

The top row has the colors (front right to left) dark green, tan, light green/white, light green in the first four holes,

Black/White (ground), grey/black, brown/white, dark green, yellow (my switch 12+v), orange (my constant 12+v) in the next six.

In the bottom row, the first six are: Black/White (another ground), empty, empty, blue green, empty

The last 4 on the bottom row are: black, blue, brown/white, brown.

why not just get a harness .its easy that way

 

[JaceHouse]

There aren't any places around me that has a harness for it. I would order it, but I'm doing it for a friend who lives about 17 hours away and he actually leaves tomorrow. So, I'm seeing if I can't figure it out for him.

Thanks for the link. I have that though. My colors don't coincide with it though.

THIS is what I'm working with.

show me the end of the plug

Not to be a wet blanket, but I would really wait until you got a wireharness... It is going to be a much cleaner install that way, and you can put the factory deck back in if you are going to resell the car much easier if the factory plug is attached.

Did you check walmart for the plug? They normally carry that particular one.

 

[JaceHouse]

I would if it was just for me @ West, but my bud really wants it.....and I'm holding the plug in my hand at the moment.

@ Pro-Rabbit. Wal Mart was all out. My walmart is silly and usually doesn't stock anything for models newer than '99.
