Very easy to install Review: Good quality product - After shorting out an electronic part on my trolling motor, I decided to install a cut-off switch so when I hooked up my battery charger or worked in the battery bank compartment, there was no way that could happen again. Works exactly as I expected. Like the "dust cover" on the key. I attached a piece of lanyard to the key and to the boat just in case it vibrated out on the road.
