If it's the receptacle on the dash, probably not that difficult, depending on the position on the dash, and how much disassembly is involved. There are probably lots of inexpensive comparables to the OEM cigar lighter available at places like NAPA, O'Reilly AP, AutoZone, etc.
If it's the wiring, and you have to trace it behind the dash, it gets more complex (or not) depending on the amount of disassembly required.
If you aren't game to try it yourself, get a quote for it at a Ford dealership.
Or, a car audio installer could probably give you a quote, too.
btw, do you have any pics of your rig? I tried googling it, and can't find any. Unless it goes by another name or description. Manufacturer name? Is it Majestic?
Just curious what it looks like.
