Review on Jtron 12V DC 50A Blue Car Start Switch Button: Ignite Your Engine with Style by Robert Grimm

I was a bit upset that there were no instructions so I had to play a guessing game with the wiring until I got it right and it looks fantastic and works better than the other release button I had previously. If you want to know the wiring is 1 for the power supply, 2 for the accessory you are connecting the power to and 3 for the ground connection. My other start button had 4 pins which made it difficult to connect, but it was pretty easy if you got it right.
