Undid the 4 screws that held the range hood in place. Unscrewed the metal panel that covers the electrical connections. Cut the two wires holding the old light fixture in place. Pulled out the old light fixture by unscrewing two small screws. Inserting the wires into new fixture was tough because it was not obvious what to do. No instructions came with the new fixture. Used a very narrow flat screwdriver to push down on the bottom of the metal connections visible in an adjacent little window, Entire effort took about two hours.
