Wire fishing

So I bought one of those Amazon light bars for my RZR. I have the SDR cage and roof. I also bought those adjustable mounts from Amazon. I have about $150 into the entire deal… I have to say everything looks good and fits nice. Yesterday I mounted the bar but didn’t wire it to the switch yet. I did put power to the bar just to see it turn on.

Here is my question, would you guys just zip tie the wire to the cage, or would you drill a hole and fish it? Would love to post a pic, but for some reason I can’t.
