First off welcome to the family from Texas.
All I can tell you about the OEM switches are they are a real bit-ch to remove. So be patient and calm when doing it.
As an example, I wanted to add a cut off switch to my radio and any other add on like a GPS to eleminate battery drain. I got fed up with trying to manipulate a switch blank off out so I just drilled a 3/8 hole in the cover and pried the some da bish out with a pair of channel locks stuffed in the hole and badabing. Lol.
