Which wires give constant, ignition and ground on a 2016 Ford F-150?
On a 2016 Ford F-150, take constant power from the Green/Red wire at the BCM 22-pin plug G, pin 22 and ignition from the White wire at the BCM 22-pin plug A, pin 16, 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 2016 Ford F-150, the second year of the aluminum-body truck. The engine lineup did not change from 2015: the 3.5 V6, 2.7 EcoBoost, 3.5 EcoBoost and 5.0 V8, all with a six-speed automatic. Push-button start was standard on the Lariat and above and optional on the XLT, so a fleet can easily run both kinds side by side. The power section below covers each.
The wiring was first documented on a 2015 truck and matches a 2019 installer table on every wire, and iDatalink treats 2015 to 2020 as one install. For 2016 in particular, iDatalink's own 2016 F-150 install guide confirms the gateway plug wires, meaning the constant, the ground and both CAN pairs, and Ford's 2016 owner's manual gives the fuse numbers below. Our team has not yet metered these on a 2016 truck, and each row says so.

Where do I get constant, ignition and ground on a 2016 Ford F-150?
Take constant, ignition and ground from the same area. Push-button trucks get all three at the body computer. Key-start trucks get all three under the driver side dash, where the gateway plug and the ignition switch sit a few inches apart.
Option 1 Push-button trucks
At the BCM
Body computer, which is also the passenger fuse panel. Right side of the passenger footwell, behind the kick panel trim.
Constant
Green/Red
BCM 22-pin plug G, pin 22Always hot. The main BCM battery feed, on a 50A fuse.
Ignition
White
BCM 22-pin plug A, pin 16Push-button trucks: "Ignition Sense", hot in run. From a 2019 push-button table, not yet confirmed on a 2016.
Ground
Body ground
No ground wire listed at the BCMUse clean body metal in the passenger kick area. Never the battery negative post.
The constant here has the biggest fuse on the truck. On key-start trucks Ford's police guide shows the ignition cavity (pin 16) empty, so key-start trucks use Option 2.
Option 2 Key-start trucks
Under the driver dash
Gateway module on the back of the OBD port, plus the ignition switch on the steering column.
Constant
Green/Red
Gateway module behind the OBD port, black 24-pin plug, pin 24Always hot. Confirmed for 2016 in iDatalink's 2016 F-150 guide. It also feeds the gateway, so keep the load light.
Ignition
White/Orange
Ignition switch, black 7-pin plug, pin 1Hot in run and start. On the steering column, a short reach from the gateway plug.
Ground
Black/Violet
Gateway module, black 24-pin plug, pin 14Module ground, same plug as the constant.
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 of the switch. Pins 2, 3 and 4 were not found in any source we checked.
No engine computer option on this truck. Ford's own upfit guide for this generation says not to connect anything into the PCM or its harness, because it can affect engine and transmission operation. Power pins from an installer-reported 2015 wire table and iDatalink's 2016 F-150 install guide.

Which years share wiring with the 2016 Ford F-150?
This page2016Same four engines and six-speed automatic as 2015. Ford's 2016 fuse chart matches 2015 on every fuse listed here.
Same wiring2015, 2017, 2018, 2019 and 2020iDatalink puts 2015 to 2020 trucks in one install, and installer tables from 2015 and 2019 trucks match on every wire here. Ford renumbered the under-hood fuse box for 2018, so check fuse numbers on each year's page.
Not this page2014 and older, 2021 and newerThe 2014 truck is the older steel body. The 2021 truck is a new generation with a different ignition switch plug.
Where are the fuse boxes and ground points on a 2016 Ford F-150?
InteriorPassenger fuse panelThis is also the BCM. Right side of the passenger footwell, behind a trim panel. Fuse 18 (5A) feeds the ignition switch. Fuses 12 (7.5A) and 15 (10A) feed the gateway module. Fuse 36 (15A) also feeds the 360 camera module on trucks that have one.
Under the hoodPower distribution boxIn the engine compartment. Fuses 89 to 92 (20A) are the power points, 110 (10A) is 4x4 run/start, and 113 (7.5A) feeds the cameras and blind spot.
Ground pointsNot publishedWe found no Ford list of ground points for this truck. Use clean body or chassis metal, never the battery negative post, and never remove a factory ground.
Fuse numbers come from Ford's 2016 F-150 owner's manual. Our team has not yet checked them on a truck.
