For lighting the complete lighting package, do not offer a harness at this time, but a custom harness is in the works! We only offer the wiring harness for the FRONT Light Bar. For the Side Lighting options, please see below.
The best place to start on getting your roof rack wired up would be to contact a shop in your local area, look for a shop that does 12V wiring. Look for an automotive accessories shop or a 4Wheel Parts store or equivalent that also does installations. We can't recommend a particular shop as everyone's quality of work differs. We highly recommend asking the shop for examples of their work before hiring them to wire your rack. A poor wiring job can result in a fire, so make sure you research them properly!
