It should be at the back of the driver-side fender inside. I beleive the wire is black with a red stripe. Take the screw out, clean up the metal, and screw it back down tightly. You may want to add some electric grease around it to prevent it from corroding again right away.

Look at the negitive battery cable.
There is another wire connected there. trace it down to a quick disconect. and unplug it you will find it coroded....... clean and / or cut it off and replace it with a butt conector.
Try un-pluging the relay and clean the conections as well.......
