So how did this turn out? I think I am going to be doing the same thing tomorrow. Only I have a Hella 1000 black magic kit that I am mounting on the brush guard.
I assume that your talking about going though the firewall where the factory flex hose goes though the rubber sealed hole. I wish they left a few more holes for us anyway....I mean the chances that we are putting a few lights on an H2 are pretty good I would think.
I am going to put my switch on the back of the dash...so I will have to do a reach around.

The way Hella wants them hooked up is to only run with the highs.
