Hello Kent, thanks for reaching out. I do have an option for you, but there actually are no custom fit wiring options for the 2017 Ford C-Max. We do have a universal option that can be used. Take a look at the following:

- ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT

This is a universal 4-flat harness that can be used on virtually any vehicle. It uses clamps that go around the wires and detect electrical pulses. So you can add trailer wiring without any cutting or splicing of the vehicles harness.

The video I linked below will show you an example of installation.
