if you are trying to install the factory stereo to it...it should be the same plug...if you are trying to install the stereo for a cougar on a different car you need to buy the plug for that stereo and then a harness for the other car...
By diagram do you mean the wire color scheme? You can find this in a stereo installation kit for you car. Take a pen and write it down. I will search for it and post a picture, if you respond. F. Garay
