Your 2010 GMC Terrain does not require a converter for the 4-way trailer wiring. I do always recommend using a powered converter if one is available. Which for your Terrain the Tekonsha T-One Vehicle Wiring Harness # 118494 is available.

For me the converter is protecting the factory wiring harness if there was ever a failure in the lighting system on the trailer. It also cuts down on the amount of power going through the tail light wiring on your Terrain. While it does require extra steps to install than a system like the Curt # 56094, I prefer the piece of mind that it is not damaging my factory wiring.
