For my Volvo I got an adapter from etrailer.com that plugs into the factory harness at the taillight pigtails. No cutting or splicing wires. It has a separate 12v connection to power the trailer lights so it doesn't change the load on any of the factory brake/turn/parking light circuits.
I have also seen adapters that clamp on to the wiring and detect current by induction. I'd try to avoid splicing directly into the wires, either with cutting/soldering or "quick splice" crimp-ons that pierce the wire insulation. Does the dealer sell a wiring adapter for trailer lighting?
