I know that questions regarding the installation of a second battery
have probably been addressed one thousand times over but I'm new to this
and really nervous about doing this wrong.  Here goes:

Yesterday, I started pulling apart my van with the intention of
connecting the second battery that I have under the driver's seat.  I
have a 1980 Westfalia.  It's the Canadian model so, according to my
research, it would have shipped with a second battery installed.
According to the pretty diagrams in my Bently, there should be a couple
of grommets in the bottom of the battery compartment under the driver's
seat that the wiring would have originally passed through.  There are
none.  Again, according to Bently diagrams, there should be a threaded
hole just slightly under the drivers seat to which the braided ground
strap would have fastened.  Again, there is not one.

I had intended to run a nice big cable from that battery compartment
back to the engine and connected it to the relay that I purchased.

Now, I am nervous.  I don't really want to start drilling holes through
the body of my van.  What else can I do?  How can I ground the batter to
the frame is that threaded hole is not there?  Am I missing something
really obvious?  Help!
