The connectors had two issues that worked for me but probably weren't the best in other situations. The top auxiliary connector is extremely flexible, so if used in a situation where there is movement, it most likely won't last very long before breaking. The main connector that connects to the main power supply is a little loose, so it may slip off in a vibration situation. I used it in a situation where there is almost no vibration and movement on the back, so it worked for me, but next time I will definitely buy something more permanent.
