Related to this thread, my '87 Westfalia (full camper) doesn't have the second
battery installed, but in the compartment under the driver's seat there is some
wiring and a square relay attached to the upper right corner. I don't see any
battery cables, however, just the relay and some wiring.

Can anyone confirm that this is the relay for isolating the two batteries? If
so, is the Hella dual battery kit I just ordered going to be redundant?

Thanks in advance!
