Subject:Re: Aux driving lights question..best easy power source..?

I used Hella XL driving lights and ran the power to my relay directly from
the secondary battery, but it's just as easy to run a lead wire from the
main battery, through the vent tube and under the vehicle.  I eventually
used the same wire to power my triple Mercedes S-class horn.
