Thanks for your enquiry.
We do not sell a kit which includes everything with our light strips. The main reason for this is there are many ways in which lights can be connected and everybody has a different idea/reason as to how they want things done.
We do have a wiring harness that we sell with some of our lightbars which you could use, however some small amount of modification may be required depending on your application.
There are two harnesses available. One with switch and fuse for $17 and the other with switch, fuse and relay for $24 (normally $29).
We also have an LED strip available that can be cut every three LED's allowing you to custom make a length. They are not on our website at the moment but I can do these for between $13 to $19. Price is dependant on how many LED's you want per length.
If you have any further questions let me know.
Cheers,
Paul
