Great product-lousy installation instructions
The power lock works great but the installation instructions are complete crap. It may be better for other makes or other years but for my 2013 Silverado, the wiring connection instructions were wrong. The wire colors in the instructions are not the same as on the truck. But after you figure out which wires you need to patch into, it isn't so bad. I posted a photo of the wires that I needed to patch into on my truck.
