Light bar wiring

Hey guys, just about to wire up my light bar but I'm not how to route the wire into the cab for the switch. For those of you that have done it can you point me in the right direction?
Thanks

 

There is a grommet on the driver side from the engine bay to the cab. That’s where I’ve wired all mine through.
Plenty of YouTube videos.

edit: I tapped my wires to a ratchet extension to push through to the driver side floor board. May or may not have to make a small slit in the grommet to fit

 

Thanks I made a small slit in the grommet and pushed em through.
