unplug it and plug it back in
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...
You plug it in.
the ACC wire from the stereo is connected to constant power (+12V)
There is a number of ways to do this. First is to purchase a FM transmitter. The transmitter is a small unit that pugs into the cigarette lighter and has a plug that goes into the MP3 players headphone jack. you set the car stereo channel to the broadcast chennel set on the transmiter and you then can listen to the mp3 player on the car stereo. If your car stereo has a external input plug you can use a cable to connect the player and stereo.
Yes it can.

You will be able to plug in, however there is only one jack featured on this system.
Yes. Of course you can. I recommend going to Walmart of or any other store that sells car stereo do it yourself products and buy a wiring plug for that year of car. You match up the wires on one end of plug to factory wires under dash and then match up wires from back of CD player (stereo plug) to the wires on the other side of plug. Then connect the plugand insert player. The factory wires will not match up to the wires from stereo plug and can be confusing (because for example there are 5 factory wires that you will need to match to the 3 stereo plug wires just to get power to the deck) and this way you won't accidentally hook wrong wires up and possibly fry your deck or cause a short in the car's electrical system.
That depends on the amount of pins the old and new stereo have - the "pins" are where you plug your wiring into in the back of the stereo and not all stereos have the same number of pins. (But wiring adapters with the suitable number of pins can be bought)
You could have shorted the stereo out, if so there is no way to check that. You might have to get a new head unit. Two wires have to have power in order for the stereo to power on: the 12 - volt constant (this gives power to the stereo even when the key is off for clock and setting memories) and the 12 - volt switchable (which tells the stereo the car is on and powers up the stereo). Remove the stereo plug from the back of the stereo - if two of the wires in the plug have power when the key is in the on-position (use a test light grounded to something metal) then the stereo is bad. If only one wire has power, you have a bad fuse or bad wire. If the constant wire is bad, simply jump a new wire to a constant fuse on the block such as the horn fuse (or run it straight to the battery and use an inline fuse). If the switchable wire is bad, tap into a wire at the fuse block that switches off with the ignition.
