IMO, No, it won't be 'happy' with the extra current, resulting in lower
voltage to your driving lights and eventual ignition switch failure. My
suggestion would be a relay (almost all modern driving lights come with
them, so they are readily available at any parts store) getting it's power
directly from the charging circuit (through a fuse). Then the source for
the switched control voltage can either be the ignition switch, or (my
favorite) the high beam headlight circuit. If you can't find a relay
locally, Whitney sells them for about $6.

Assuming you are talking about the two holes between the steering column
and the outside of the car, the one closest to the steering column is
supposed to be the heater fan, the other one is the OD switch. On cars
without OD, it was originally covered by the dash vinyl.
