Well wiring into the igntion, brake switch, parking lights is the cake part. It's the stupid transponders in the keys that suck. If you have the big fat ford key you probably have a transponder in it. There is 2 ways to bypass that. 1 is to get a transponder module which there is 2 kinds, the first one you need to put and extra key inside the module and there is a loop that you wrap around the ignition so many times, the other still has the wrap thing but instead of using the key, you program the transponder signal into it. OOORRRR, there is the getto way like we used to do it at my saturday job when those stupid things first came out, where you pry out that little door on the end of the key and pull the transponder out, then just glue it ignition switch in the right spot and there you go, instant bypass. Oh yeah with that you have to take the transponders out of all your other keys cuase the 2 transponders cancel eachother out. But the wireing to the ignition is easy, just get a test light and cycle the key and you'll find the wires you need to use.
