If you lye on the floor and look up the brake pedal arm, you should see a switch that is about 6" up. Its only visible by looking under the dash. There's about 5 or so wires going to it. Then again mine is a 93 and a stick so it might have different colors and number of wires.
As for the radiator; watch out for the china knock offs. I never bought one but when mine went I read a lot about them busting apart just from the vibration and the old ones the guys took out were better. The one I bought was made by a company that also makes them for Ford. The name starts with a V but, I don't remember the exact name. After searching for a while for a good one, I bought mine from a radiator shop.
