There should be a rubber grommet that leads to your glove compartment.
But i have another question for you:
- Will this be the only lights you will add ? or do you plan to have more in the future ?
The reason is this, i recently came across the Auxbeam switch panel and must say although it is not super cheap, i was extremely impressed with how easy it was to install multiple lights or other external items.
Have a look here:

So far i have always done my own installs by buying the relays, wiring, fuses, etc.. but even though i do my best, after a couple of years, and a lot of heat and sand, those wires became brittle, and the relays started to fail.
The fact that this is a one-stop solution with IP65 rating really could be a life-saver. Installation over the weekend with a helper and a good beer
