Which wires give constant, ignition and ground on a 2024 Ford Ranger?
On a 2024 Ford Ranger, take ignition from the Green wire at the underhood fuse box, 10A fuse, and ground to clean, bare body metal. Meter every wire first.

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 Ranger, the first year of the new generation, US market.
The colors come from Ford's 2024 Ranger body builder book and 2024 installer posts. Our own team has not yet metered these on a 2024 truck, and each row says so.
