That depends on how you want them to work. If you have the backup lights working you can tie into your harness under the truck are behind the light it self and ground them. They will only come on when the truck is in reverse though.
If you want them to work anytime you will need a wire from the battery to switch on the dash to the lights on the back bumper.
It all depends on how u want them to operate.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
