Which wires give constant, ignition and ground on a 2011 International DuraStar 4300 and 4400?
On a 2011 International DuraStar 4300 and 4400, take ignition from the Pink wire at the cab fuse block (inside the cab), ignition relay output, circuit A13FC, 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 2011 International DuraStar 4300 and 4400.
Navistar tells installers not to take power at the key switch on this truck. It gives relay output circuits in the cab fuse block for ignition and accessory, and those are the wires on this page. Navistar identifies wires by circuit number, and the colors here come from its color chart for each circuit number. This is the system Navistar calls the 2007 electrical system, with a Body Controller. Lamp wires are at the body builder connector. Our own team has not yet metered these on a 2011 truck.

Where do I get constant, ignition and ground on a 2011 International DuraStar 4300 and 4400?
Navistar gives ignition, accessory and ground at the cab fuse block and the dash panel. Constant power comes from the Mega-fuse.

Cab fuse block (inside the cab), ignition relay output, circuit A13FCNavistar's tap point for key-on power.
Accessory
Light Blue
Cab fuse block (inside the cab), accessory relay output, circuit A12BNavistar's tap point for accessory power.
Ground
Ground stud
Ground studs on the dash panelNavistar says to ground added equipment to the chassis or to these studs, never to the batteries. Ground wires on this truck are white.
Tap points from Navistar's body builder electrical book (October 2012). Colors from Navistar's circuit color chart: circuit 13 is the pink ignition feed, circuit 12 is the light blue accessory feed and ground circuits are white. The book gives the circuit number at each tap, so go by the circuit number and meter it. Navistar says not to connect to the key switch itself.
Option 2 Constant
Battery feed
Navistar's battery connection for added loads.
Constant
Fuse stud, color not published
Mega-fuse, unfused side, through an inline Maxi fuse holderNavistar's battery feed for added equipment. No more than 45 added amps and no more than 3 ring terminals on the stud. Battery feed wires on this truck are red.
From Navistar's body builder electrical book (October 2012). Fuse the new wire as close to this point as you can.
This truck is multiplexed. Navistar identifies every wire by circuit number, and the colors here come from its color chart for each circuit number.
