AnswerHere is a good installation guide that might help you in deciding and knowing how to hookup the radio that you have.

Here is another wiring chart that may help:

According to this pdf file:
http://www.issford.com/issford/radio_guide.pdf
the radio you refer to is out of the 2001-3 Excursion Ford. Whether it is compatible or not I don't know, but if the unit has the right outputs, etc. and power connections you should be able to make it work.
If you are still pondering over it may I suggest you get a second opinion from Ernesto R who knows these radios better than I:
