Product review (5 stars): Worked great.
Not a big problem installing this.  To gain access to the underside of the cooktop I put this on, there are only 2 screws - open the oven door and they are on the underside of the corners to the cooktop.  Then you can lift the cooktop up.  There are two wiring connectors - one on the left and one on the right at the rear of the cooktop.  Then unscrew the ground wire.  The whole cooktop is then free to move to the workbench.  The burner's spades were oriented a bit differently but they still fit the wire (two larger spades, two smaller spades.  I figured that since it was AC power, it wouldn't really matter which wire plugged in where, as long as I fastened them into their appropriately sized spades on the burner.
