When it comes to installing trailer wiring on your 2017 Chrysler Pacifica The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118712 is confirmed to fit your vehicle.

The trailer harness has a simple plug and play installation that plugs into your vehicle's wiring harness, which is located behind the driver and passenger side tail lights. The harness will come out as a 4 pin flat connector.

To make the 4 flat connector to a 7 pin round connector The Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 is needed. This piece will attach to your 4 flat connector and make it into a 7 round and 4 way flat. Three additional wires will be included as follows:

Black - 12V hot lead
Blue - Electric Brake
White - Ground

If your trailer has brakes then a brake controller is needed. The Redarc Tow-Pro Liberty Brake Controller - Proportional # RED24FR will work for you. This controller can be installed in an out of the way spot so its not taking up space on your dash board. The control knob is visible on the dash to help control the controller. This controller has a 3-axis accelerometer that measures deceleration in all directions for precise braking and a smooth, uniform stopping action. The Universal Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers # RED69FR.
