I am preparing to wire up my auxiliary lights in the front and was wondering what the best way to pass the wires through the firewall to put in the dash switch is????
Find somewhere convenient to drill a hole of the correct size to allow insertion of a rubber grommet. The grommet ID will depend on the size wire or wires you're using, the actual hole size dictated by the selected grommet.
Debur the drilled hole both sides then be sure to coat the bare steel with some sort of rust inhibiting paint etc.
I've done this on the driver's side, pulling the cardboard-like material away from the firewall first before drilling holes. Once the grommet is installed and wires pulled that material is put back in place somewhat protecting the added wiring from feet on the pedals possibly contacting or disrupting it.
I did this on the driver's side since that's really the only somewhat clear space both inside the cabin and on the engine bay side. Passenger's side houses the heater & A/C components.
Usually there's a rubber boot around things like the steering column shaft you can poke through and then just seal it back up with silicone. I have a few things going through there, can't remember where I routed my fog and drive lights, but I know I was able to find a spot without drilling, I'll have to take a look.

Wait for night time, shine a strong light in both foot well then look in the engine bay if light pokes through. That's how I found mine and saved me from drilling extra holes (as they can be blocked by components but still usable).

If this is a ford van there are already 2 unused wires run though the firewall exactly for this reason. If that's all you need, then search upfitter econoline. There is a pdf out there showing wire locations, and also extra positive lines to use (constant power & ignition power). All 4 are up by the power steering reservoir, and 2 of them than can be used for anything end up by the brake controller wiring the other side of the firewall.
