Ok yes u need to wire these controllers and if you do not have the required skills and confidence needed to,perform the build dont . I have included a link to one of the shorter how to videos on utube . I believe that a person should tin the end of the wires were they are installed into the controller and all the connections also . Tinning is when u twist the end of the bare wire and apply solder to the end . All of these products are designed with solid wire connections in mind , so tinning the ends makes the wires solid . If you are not sure about ( tinning ) look it up on utube . also when installing tinned wires in conntroller be sure to trim the ends until they are just long enough that they hit bottom with no exposed wire I am including a few pics of tinned and untinned wires and a close example of how they should look short exposed short end typical for controller install hooked end typical for install around plug end screws .
