OK I now understand your needs. Here is a link for an 6cd swap into a Mercury Marauder.

This radio is from a Ford escape and will definitely fit with a little effort.This radio has the gray "phase 2" Plugs and sub woofer output like yours requires and would require the reverse harness adapter to fit the black "World plug" connectors on your Explorer. The radio bezel may minor fine tuning but it will fit with just a little effort. Once again the radio is out of a 2005-2006 Ford Escape and is model number
"6L8T-18c815-FD or FC". Please read the tread and it has a lot of info including how to hook up an auxiliary to this radio and the radio also has the "Sat" feature. Many people such as those on this Marauder website didn't want to lose the factory look of their vehicles but wanted to upgrade their older Ford radio to the newer type 6cd radio with more features. Good luck and feel free to ask if you have more questions.
