Push on connectors and switch housing were different

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 change the push on connectors. For me, the actual switch was what I wanted and I fixed it my way. It was easy to do however some folks may want to change the push on connectors. Works great and saved me hundreds of dollars. Thanks.
