The instructions are ok, they tell you the color and stripe of wires you are looking for, but they don't tell you WHERE to find the correct wires. I had to watch a few videos online to figure it out. But the tailgate unit installs very easily, and once I had run the wire (the biggest challenge after finding the wires), it was very easy to finish up the installation. Works like a charm.One note, if you buy this on Amazon, Pop and Lock will not warranty it. They specifically exclude Amazon purchases from the warranty. I called them about this, since I wanted to buy it directly from them. The Amazon unit was $90 (and Prime shipping). The same model number on the Pop and Lock website was $120. I would have paid the higher amount, but then Pop and Lock wanted to charge me $20 for shipping! So I called Pop and Lock to see if they would work with me, at least on the shipping. No deal. They wouldn't even discuss it. At a total of $140, I just couldn't justify buying it from them. So I bought the one on Amazon and very happy I did. Even if the actuator fails, I could buy another actuator on Amazon for $10.
