Which wires give constant, ignition and ground on a 2024 Ford Expedition?
On a 2024 Ford Expedition, take constant power from the Purple/Red wire at the brown 17-pin plug behind the glove box, pin 7, and ground to clean, bare body metal. 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 2024 Ford Expedition, the last year of this body, including the long-wheelbase Expedition MAX and the SSV special service truck.
The 2022 refresh moved the data and power taps behind the glove box. The only wire sources for these years cover those plugs, so most circuits show Not found. The guides list push-button start only for this year. Our own team has not yet metered these on a 2024 truck.
