So I took Hotrod Lincolns advise and purchased a better quality battery disconnect switch from my local flaps. A little expensive but the difference was obvious. I decided to mount it on the transmission cover back next to seat. I took a gasket punch to take care of cutting the carpet so when the key is removed it is very inconspicuous.
