Factory Stereo

I recently decided to sell my car and I am in the process of returning it all back to factory stuff. When i got to putting the old stereo back in I had a problem. There are 2 factory plugs; 1 for power, ground, ect. and the other for the speakers. The power plug goes into the stereo itself, but i can figure out where the speaker plug goes. The matching plug for the speakers in the dash has 4 bridged wires, making it go no where at all. Does any one know if there is another plug or where it goes, cause i just cant figure it out. Also I have some things from my car for sale to. 17" chrome rims with ZRi tires, kenwood deck, and a Kicker L7 in a custom box. Thanks!

sure its speakers? maybe a thing for the cd changer? ford adds a lot of wireing even if the part arnt there

No, the cd changer and the stereo both have power and work, just no sound. I used a volt meter to check the wiring, and the harness with the speaker wires is the one with no place to go. Its really frusturating!!!!!!
