Which wires give constant, ignition and ground on a 2021 Ford Escape?
On a 2021 Ford Escape, take constant power from the Brown/Red wire at the gateway module plug C2431 (black 24-pin), pin 24, back of the OBD module, driver side dash, and ground to the Black/Blue wire at the gateway module plug 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 2021 Ford Escape.
The fourth generation runs most body signals over the data bus, so we have the gateway plug, hazard and a few tail lamp wires. Our own team has not yet metered these on a 2021 vehicle, and each row says so.
