what colors did you find? Have you attempted to use a meter to try to figure out which wire is which?

What exactly are you trying to do? If changing the radio, they do make a harness that sells for 15 dollars on the mainland. If you have that harness, the wire colors match up with the wire colors of your aftermarket deck. ------------- Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

Yes I'm trying to change it with a after market. Yeah but I was hoping to just cut the factory ones and install it straight. Normally I would but the harness for after market stereo but right now I'm going to install with out it. So I'm looking for the diagram. But every where has the wrong colors.
So asking around everywhere and this forum is my last hope.

Yes the rear seat has controls.
I saw that same diagram on a site. But my color wires don't match thoes. (ex. I don't have a GREEN/ violet.)

Are you sure that all 3 of those plugs were plugged into the back of the radio? Can you take a picture of the back of the radio and post it? Have you looked in the center console to see if you find a factory amp? ------------- Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

Yes It seems that there is a factory amp in the trunk. Yes im sure that all of them plugged into the back. I will take a picture and post it, it might be low quality as i will have to take it with my phone.

Do the wire colors on the factory amp match the colors of the diagrams you have found? A phone pic should do just fine.

I tried to take a pic with my phone but I couldnt email to myself for some reason. so i drew (a ugly picture) of the back of the radio. The two circle are where the radio thing and this only thing went into. and the others are the three harnesses. [IMG]https://img.photobucket.com/albums/v520/02Sakura/radio.jpg[/IMG]

Pay attention to only the left plug in the following diagram. You have an amplifier in that vehicle, chances are you are going to have to bypass the amplifier if you want it to be engine noise free. | POWER 1=Permanent Live 2=Ground this pin 3=IGN live 4=Illumination 5=N/C 6=Ground 7=Electric aerial |
Following is the pic you posted, has anyone ever seen an amp preamp plug with 12 wires on it. I am sure it has to go to the rear controls. You do know you are probably going to lose the rear controls if you do this. Disregard the question about the 7 pins.

Yes my amp harness looks like your picture one side 1-6 and the other 1-8 1.Orange 2.Black 3. White 4. blank 5.blank 6.blank 1-8 all the speaker wires. How do I bypass the amp? Do I tap all the power, Ignition, ground, and speaker wires from the amp harness instead of the harness that pluged into the factory radio? if so how do I knoe which speaker wire is positive and what it negative? I know the 1-8 goes in pairs like 1&2 is Front left, 3&4 is Front right, etc but does it also go positive and negative, positive and negative? or negative and positive, negative and positive? its ok if i cant controll it in the back, the back controls stopped working long ago anyways. haha

Ok ill give that a try. Also I I want to install my sub and amp, so I hooked it up like this 
I connect the sub (#1) to the Speaker output left + and - right [labled bridged](#3) my right + and left - is empty. I connect the RCA from the deck to #2 [line in] on my amp line out is emtpy I connect Power, Ground, and P.con (#4) Power to battery, Ground close to amp, and P.con to the IGN wire of the deck. How does that sound? correct?

That sounds correct, assuming you have the correct terminals on the back of the radio.

It sounds like you are on your way, but here is some more info: https://www.nicoclub.com/FSM/quest/1996_Quest/el.pdf Go to page 172 and it will list all the wire functions and colors for the radio. It will also denote postive and negative speakers connections! You should be able to figure out the wire colors by their abbreviations, with the exception of blue - they abbreviate it "l". ------------- Kevin Pierson
