I removed the 4 screws that held the element in place with the oven door still attached. I attached some twist wire to the connectors so that they would not fall behind the oven’s rear wall. I had a harder time installing the new element assembly with the oven door attached, so I decided to remove it. That made it easier to reach in and attach the new assembly. All 4 connections were simply attached and the assembly was screwed into place.
