The switch housing was not exactly the same for easy snap in. I removed the actual switch and installed it into the old housing. Then I found that the male pins were larger than the old ones. I chose to clip off the female connectores, strip the wires, and solder the wires to the pins on the switch. It was easier for me than attempting to ... Read more change the push on connectors.
