Courtesy lights install question.

[custom10nut]

I'm about to install my under dash courtesy lights.
My question is this
What is the best way to drill the holes to route the wiring for the door jamb switches?
From what I can tell I have to go through the door jamb, the inner cab panel and then the kick panel, up under the dash.
Is there a way to get around the panel that's in between?
I might take a trip out to my favorite salvage yard to look at one of the bare cabs.
