Which wires give constant, ignition and ground on a 2017 Ford Fusion?
On a 2017 Ford Fusion, take constant power from the Gray/Red wire at the gateway plug on the back of the OBD port, black 24-pin (C2431), pin 24, and ground to the Black/Blue wire at the gateway plug on the back of the OBD port, black 24-pin (C2431), pin 14. Meter every wire first.
Written by API Signal, fleet GPS and camera installers for 35+ years across Georgia, South Carolina and North Carolina, installing every major telematics and camera brand. Every wire on this page lists its source.
Test every wire with a meter before you tap it
No wiring information is ever guaranteed. Colors and locations change with trim, options and build date, and the manufacturer can change them in the middle of a model year. We share this as a starting point for installers, and you are responsible for confirming every connection on the truck in front of you.
This page covers the 2017 Ford Fusion, the restyle year, including the Hybrid and Energi.
The only wire source made for these years is an iDatalink guide, so this page is short: constant, ground and CAN at the gateway plug behind the OBD port, and the park light trigger. Door, brake and reverse colors are carried from 2013 and 2014 cars and are marked that way. No ignition wire was found. Our own team has not yet metered these on a 2017 car.

Gateway plug on the back of the OBD port, black 24-pin (C2431), pins 20 and 19The OBD socket is part of the gateway module, so there are no loose wires at OBD pins 6 and 14. A slower CAN pair is Gray/Orange and Purple/Orange on pins 23 and 22. Ford says never to splice the CAN wires.
Sources: the iDatalink install guide for 2014 to 2020, plus 2013 and 2014 wire lists for the door, brake and reverse colors, carried only where a copy of Ford's 2013 to 2020 workshop manual gives the same plug and pin. Most circuits were not found for these years.
