Your car most likely had a premium sound amp from Ford. This either can be bypassed, or interfaced with.

If they have been cut already, best to get an amp bypass cable.
These guys sell the 70-5513 part on-line;

This link also shows that you can unplug the OEM premium sound system, and then you could use that plug like the basic install shows.
