Yes, indeed. You can't just wire the trailer lights in parallel with the
car's rear lights because that will upset the bulb failure unit - which is
presumably the 'relay' to which you refer. That doesn't mean that you *have*
to use the official Volvo wiring kit - there *are* satisfactory
alternatives, as long as you - or whoever installs it - knows what you/they
are doing.
Most current third party systems provide their own relay, which is triggered
by a very small current taken from the existing lamp circuits, and thus
doesn't upset anything. My 2007 V70 is equipped with such a system.
