I bought this item together with the wiring harness and switch. It is made of fireproof material and is quite durable. But you don't need it! The switch I'm using was designed with flanges that attach to the back of the switch that you will mount your switch on. I give it five stars because it's well built and seems to work very well. Also, I was tired of returning it but the return shipping fee was the same as the product. I just throw it in the trash can. Maybe one day I'll use it for something else.
