Which wires give constant, ignition and ground on a 2022 Ford F-650 and F-750?
On a 2022 Ford F-650 and F-750, take constant power from the Blue/Red wire at the underhood upfitter connector C201 (16-way), left side of the engine compartment, pin 8, ignition from the Gray wire at the same connector C201, pin 9, and ground to clean, bare body metal. Meter every wire first.
Meter every wire before you tap it. Colors change with trim and build date.
Where do I get constant, ignition and ground on a 2022 Ford F-650 and F-750?
Ford builds customer access wiring into every F-650 and F-750 for upfitters. Use it instead of tapping the truck's own wiring.
Option 1 Easiest
Underhood upfitter connector C201
A 16-way inline connector on the left side of the engine compartment, for upfitter wiring.
Constant
Blue/Red
Underhood upfitter connector C201 (16-way), left side of the engine compartment, pin 8Fuse 27 battery feed.
Ignition
Gray
Same connector C201, pin 9Hot in run, fuse 3 (VPWR3). Ford's PTO drawing in the 2027 book shows this circuit at cavity 16, so meter both.
Ground
New ground
Clean chassis or cab metalFord's upfitter connector has no ground pin. Make a clean ground to bare metal.
The same connector has park brake (pin 1), vehicle speed (pin 10) and park-only (pin 15). Blunt-cut upfitter wires stay in the driver footwell behind the OBD port.
Option 2 Lamps at the rear
Rear body builder connector
At the end of the frame or back of the cab, left frame rail, depending on options.
Rear plug
Not confirmed
Rear body builder connectorThe pin table in this year's book is unclear, so it is not shown. Meter at the rear plug.
Ford's lamp outputs are trailer tow relay outputs. Use them as sense inputs only.
Colors from Ford's 2022 Body Builders Layout Book, with the upfitter connector pins from the 2021 and 2023 books. Meter every wire before you tap it.

This page covers the 2022 Ford F-650 and F-750 medium duty truck. Ford builds customer access wiring into these trucks for body builders, so a GPS or camera can take power and signals without cutting into the truck's own harness.
The 2022 book prints the ignition color and the brake, speed and park brake circuits as text. The connector pins match the 2021 and 2023 books. Our own team has not yet metered these on a 2022 truck, and each row says so.
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.
