I am about to install an optima behind the drives seat in my 87 camper
(manual trans).  I wanted to make sure everything was working correctly at
the relay before spending the buck fitty on the battery (PO had an aux bat
set up by rear heater which died, so I removed it long ago with all the
wiring).

The wiring seems correct according bentley (97.34a).  Here is what I have
with engine running:

30 - thick red wire, 13.8v
85 - small black/red wire 0v
86 - small blue wire 13.8v
87 - fat pinkish/red wire 13.8v
center connector - fat red wire 13.8v

Does this seem correct?

Thanks,

Jeff
