We received this for the 3rd taillight on a 2016 Chevy Silverado Truck (RV). We used butt connectors to connect the wires to the taillights. I will say that you need to connect them to both right and left taillights to work. We covered the turn signals and just used a broken wire. Worked very well but I have to say the adhesive on the back is not very strong. I would recommend finding an alternative if you want him to be liable. It doesn't have instructions, but the wire connections are pretty obvious as to what's what.
