nah, they have everything tied in from the amp in the trunk.
12v constant - white/purple
12v switched - white/light blue
ground - black/lt green.
rest will be in that cable that runs to the amp. cant find anything on the pin outs for the amp tho
first off, depends on what package you have. do you have the ford keys to pull the radio? if you do, that will help a lot. some have everything running through the factory amp in the truck under the back deck up against the back seat. If you pull out the radio, is there two plugs with wires...
checked both metra and scosche, no-one offers something for you. take a pic of your dash and I will see what I can come up with for mounting options, but I believe wiring for the radio will be the same as this. http://www.the12volt.com/installbay/stereodetail/1207.html
one thing i told my installers when pulling apart cars, is look for help on the internet. for radios check out metraonline.com. you can almost always find pictures to pull the radios out.
and for door speakers, check out this site, great for pulling door panels off...
