either way, you can go through the brake grommet on the drivers side or you can go through a grommet on the passenger side that you can easily see if you stick your head underneath the glovebox. It's easy to access if you remove the glovebox.
To get the wires through, drill a hole slightly smaller than the total diameter of the desired wires/senders to go through. Then pull them through until they seal around the edge. Use some sealant around the edge of the wires if you're concerned there will be any leakage.
