The Curt # C51170 (or any brake controller, for that matter) isn't a vehicle-specific item. It'll work on just about any vehicle that has a standard hydraulic braking system.

How you'd install the # C51170 Spectrum brake controller will depend on whether or not you have the factory 7-way trailer connector installed on the bumper. If you don't have the 7-way, you'll need part # HM11141144 which installs as shown in the linked video.

The controller installs by wiring directly to the tow package wiring under the dash. The tow package harness is located behind the driver's side kick panel just left of the emergency brake pedal as shown in the linked video. You'll need the # C51515 pigtail that connects to the tow package wires as follows:

• Blue pigtail wire connects to dark blue tow package wire
• White pigtail wire connects to black tow package wire
• Black pigtail wire connects to red tow package wire
• Red pigtail wire connects to white and blue striped tow package wire

The install video for the Spectrum will also walk you through how the controller works.
