Check engine with trailer connected

[Larry Newman]

Thanks for the explanations and tips, guys.  I'm intrigued about the
converter box.  What does it convert and what is it's advertised use,
that is, what problem was it designed to solve?

I would suggest a standard converter box.  They range in price from $29.
to
$59. and are wired up to the factory lights, but also to separate ground
and
+12V power.  The lights then just activate solid state relays and not
the
lights themselves.  Most European cars are MUCH more happy with this,
and
you'll see why if you look at the wire gauge size running most tail
lights.
