Without knowing what the model and make of the stereo are, it is hard to say. THe unit could be wired through a relay but not likely wholly powered through the stereo. You need to check the power feed to that unit and see if it is present. it should be fused, check the fuse.

you should just be able to get an adaptor harness, if the plugs are cut then good luck its a real pain. for some reason other vehicle wiring is added into those harnesses

Just a suggestion...look up stereo plug online and look at pic of it...make sure your looking at it right (whether the tab on pigtail goes in top or bottom). Write down colors and where they are...blk is ground...red is ignition...yellow is constant power or battery...blue is antenna or amp remote... orange is illumination... white is front SPK...grey is other front and purple and green are the rear..

Page 16 of the owners manual tells you the color and function of the wires from the stereo are: http://www.pioneerelectronics.com/StaticFiles/Manuals/Car/FH-X700BT_OwnersManual112712.pdf

Here is a written diagram. This site, along with many others, offer a pre-wired harness for easy plug and play installation

Aftermarket radios have a standard wiring color set. Tell me the radio model and car year/model and I can send you the exact connection scheme.

you need a ford to pioneer wiring adapter. available at any stereo shop.
