Glad to hear you got the 'sploder!
Factory fogs would possibly be the least amount of work to install (I've heard that often Ford will install the wiring for them even if the vehicle didn't get them from the factory, all you have to do is find the wiring ends an plug everything in). But I'd go looking to see if it was already set up or not cuz I had been told my Ranger had the plugs on it and when I looked, I couldn't find any such thing. My 89 Eddie Bauer BII though didn't have wiring for foglights that I found, but it was wired up for an electric T-case and premier sound system even though it didn't have either installed...
If you don't have factory wiring, then you might be better off going with an aftermarket light unless you can get factory fogs with all the wiring an stuff. If you go aftermarket, don't cheap out an get wally-world specials though, IMHO. I'd get ones from a well-known brand like KC.
