Which wires give constant, ignition and ground on a 2019 Ford Super Duty?

On a 2019 Ford Super Duty, take constant power from the Violet/Red wire at the BCM black 22-pin plug G, pin 22 and ignition from the Green/Orange wire at the customer access pigtail behind the passenger kick panel, pin 2, 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 2019 Ford Super Duty, the last year before the 2020 refresh brought the 7.3L gas V8, a new gateway module and a new upfitter interface module.

The body wire colors on this page come from installer tables taken from 2020 trucks. Ford changed the gateway and the upfitter interface module for 2020, so those colors are carried back to 2019 with a warning on each row. The customer access wires (run/start, brake, speed, tach, park, neutral, parking brake) come straight from Ford's own 2017 to 2019 bulletin. Our own team has not yet metered these on a 2019 truck, and each row says so.

Where do I get constant, ignition and ground on a 2019 Ford Super Duty?

Take constant, ignition and ground from the same area. On this truck the passenger kick panel has the body computer's constant feed and Ford's own run/start wire for upfitters, on key and push-button trucks alike.

Option 1 Easiest

Passenger kick panel

Body computer (BCM) and Ford's customer access pigtail, right side of the passenger footwell, behind the trim.

Constant
Violet/Red
BCM black 22-pin plug G, pin 22Always hot, 50A. Read off 2020 trucks; Ford changed the body electronics in 2020, so meter it on a 2019.
Ignition
Green/Orange
Customer access pigtail behind the passenger kick panel, pin 2Ford run/start output, 5A. Works on key and push-button trucks. From Ford's 2017 to 2019 customer access bulletin (Q-256R2).
Ground
Body ground
Body metal in the passenger kick areaClean, bare metal only. Never the battery negative post.
Ford's run/start wire is on a 5A fuse. Use it as the ignition sense wire, not to power a large load.
Option 2 Key-start trucks

At the ignition switch

Steering column, black 7-pin plug, on trucks with a regular key. Push-button start was offered on upper trims.

Constant
Not found
Not found at the switchSwitch pins 2 to 4 were not found. Take constant from the BCM (Option 1).
Ignition
White/Orange
Ignition switch, black 7-pin plug, pin 1Hot in run and start. Key-start trucks only.
Ground
Body ground
No ground at the switchUse clean body metal under the driver dash.
Accessory
Violet/Green
Ignition switch, black 7-pin plug, pin 6Hot in accessory and run
Start
Blue/White
Ignition switch, black 7-pin plug, pin 7Hot only while cranking
Key sense is Blue/Gray (+) on pin 5. The switch colors come from 2020 trucks.

Switch and BCM pins from installer-reported wire tables for a 2020 F-250 and a 2020 F-350 on the12volt, which agree. The run/start wire is from Ford's 2017 to 2019 customer access bulletin (Q-256R2).

Which years share wiring with the 2019 Ford Super Duty?
