Review on Saihisday AL3Z16A506A + AL3Z16A507A Power Running Board Motors for Ford F-150 F150 2007-2014 Left + Right Side - Enhanced Performance and Easy Installation! by Loren Jacobson

As per other reviews the first kit I ordered didn't work at all until I shook the board to make it work and then it sounded terrible but like the others the price is very low so I did ordered another pair. The second pair works backwards or counter to what it should and switching the wires doesn't work. We are a professional installer who tried to help customer save money. Time to install OEM and live and learn. You get what you pay for.
