I went to Radio Shack and got one of the 7805 Regulators, looks like it will do the trick perfect. thanks for all the help.

Just to give everyone an update...

the 7805 regulator was a success! This will work for all Ford, Lincoln, Mercury vehicles with premium sound. If you want do change the head unit, but want to maintain the factory subwoofer and amp, you need to reduce the voltage on the remote turn on from the aftermarket head unit from 12VDC to 5 VDC. I found a great source for all you shop owners to purchase these regulators in bulk.

The website is: WWW.Digikey.com

Phone # is: 800-344-4539

Product model # is: LM7805CT-ND

They have a $25.00 minimum order to avoid shipping surcharge, for an order of 60 pieces they were $0.456 each. My total was only like $27.00 for 60.

If you go to a retail store to buy them (If you can find them) they are about $1.50 each.

Hope this info is helpfull to everyone.

yea you *should* also use filtering capacitors on the input and output but it will probably work fine without. I do alot of ordering from digikey never had a problem...
