Vaganons (what'd you call me?),

I am getting ready to string the wiring for my aux/fog lights and have some
questions.  There is a factory installed hole (sealed with a solid rubber
grommet) in the fire wall just behind the radiator on the drivers
side.  First, anyone know what that hole was for?

I'd like to use that hole, but find myself a bit concerned about heat in
that general area.  The harness that came with my kits have 16 or 18 gage
wires, which will create a tight fit for eight wires, but I think they'll
all fit through.  Anyone know of tubular heat shields that could protect
the wires?  How susceptible is normal auto-grade 18 gage wire is to heat?

Any wire running advice would be greatly appreciated.

Thanks for your time; robyn
