Cœur 1: Le “Driver Interface” Logique (Commandes & Readouts)

This group forms the primary components of the Équipement électrique dans la cabine that the driver directly interacts with. These are the main touchpoints for vehicle control and information.

1. Composant: ‘Instrument cluster assy’ (3820010A61B) – Quantité 1
Ce (Comp 44) is the driver’s main information source. This complex module integrates all the vehicle’s gauges (vitesse, RPM, air pressure, carburant, température) and warning lights into a single unit. C'est le “affronter” de la Équipement électrique dans la cabine and is critical for safe operation.

2. Composant: ‘Combination switch assy’ (3735010C61B) – Quantité 1
Ce (Comp 30) is the multi-function stalk assembly located on the steering column. Le Driver Control Logic is centralized here: this single unit typically controls the turn signals, high/low beam headlights, and windshield wipers. It is one of the most frequently used parts of the Équipement électrique dans la cabine.

3. Composant: ‘Ignition switch assy’ (3704010-A01) – Quantité 1
Ce (Comp 1) is the main key switch. It provides electrical power to all circuits of the Équipement électrique dans la cabine, y compris “Accessory,” “Sur,” et “Start.” This is the master switch for the entire vehicle’s electrical system.

4. Composant: ‘Radio/media player assy’ (7901010A61B) & Haut-parleurs (7901015-A01, 7901020-A01)
Ce (Comp 46, 47, 48) is the in-cab entertainment and information system. It includes the main ‘Radio/media player’ (Comp 46) and the ‘Left’ (Comp 47) et 'Bien’ (Comp 48) ‘full-range speaker’ assemblages. Cette partie du Équipement électrique dans la cabine is essential for driver comfort and communication.

Cœur 2: Le “Système nerveux” Logique (Main Wiring Harnesses)

This group is the “système nerveux” de la Équipement électrique dans la cabine. These harnesses are large, complexe, custom-loomed bundles of wires that transmit power and data signals to every component.

1. Composant: ‘Instrument wiring harness assy’ (3724010A14B) – Quantité 1
Ce (Comp 13) is the dedicated harness that connects *to* the ‘Instrument cluster’ (Comp 44). It gathers signals from all over the truck (vitesse, température, pression) and delivers them to the gauges.

2. Composant: ‘Body wiring harness assy’ (3724020MA01) & ‘Right body’ (3724025MA01)
Ce (Comp 14, 15) is the largest and most complex harness in the Équipement électrique dans la cabine. It runs through the dashboard, along the floor, and to the rear of the cab, connecting the fuse box, switches, lumières, and controllers. A fault in this main harness is often difficult to diagnose and repair.

3. Composant: ‘Left/Right door wiring harness assy’ (3724030CA01, 3724035CA01)
Ce (Comp 16, 17) is the harness that runs from the cab body, through a flexible boot, and into the doors. Cette partie du Équipement électrique dans la cabine is responsible for powering the ‘Power window switches’ (Comp 35, 36) and ‘Speakers’ (Comp 47, 48).

4. Composant: ‘Function switch harness’ (3724080B14B) & ‘Overhead console harness’ (3724085Da01)
Ce (Comp 18, 19) are sub-harnesses for specific functions. The ‘Function switch’ harness likely connects to the dashboard switches, while the ‘Overhead console’ harness powers interior lights and other roof-mounted items. This modular design simplifies the main Équipement électrique dans la cabine.

Cœur 3: Le “Control Module” Logique (The Brains)

Ce groupe représente le “brains” de la Équipement électrique dans la cabine. These are the electronic modules that take inputs from sensors and switches and make decisions to control vehicle functions.

1. Composant: ‘Fuse box assy with relay’ (3722065QA01) – Quantité 1
Ce (Comp 10) is the central power distribution and protection hub. Le Logique de protection is that it houses all the main fuses and relays. If a short circuit occurs, a fuse will blow, protecting the expensive wiring and modules of the Équipement électrique dans la cabine des dommages.

2. Composant: ‘Vehicle speed signal controller’ (3802060K61B) & ‘Coolant level controller’ (3818080-240)
Ces (Comp 45, 43) are critical monitoring modules. The ‘Coolant level controller’ (Comp 43) triggers a warning light if the engine coolant is low. The ‘Vehicle speed controller’ (Comp 45) interprets the signal from the transmission (specifically for 11.00-series tires and a 5.769 rapport de pont) and sends an accurate speed reading to the ‘Instrument cluster’ (Comp 44). These are vital inputs for the Équipement électrique dans la cabine.

3. Composant: ‘Intermittent wiper controller’ (3741060-240) & ‘Flasher relay assy’ (3726030-A01)
Ces (Comp 33, 23) are dedicated relays that control timed functions. The ‘Flasher’ (Comp 23) creates the “blinking” for the turn signals. The ‘Wiper controller’ (Comp 33) manages the “intermittent” delay settings for the wipers. These simple but essential modules are key parts of the Équipement électrique dans la cabine.

Cœur 4: Le “Switches, Sockets & Lighting” Logique (Ancillary Controls)

This final group includes the various switches, lumières, and sockets that complete the Équipement électrique dans la cabine interface.
