DAF XF105 Wiring Diagram – Factory Electrical Schematics (194 Pages)

If you’ve ever chased a short on a truck at 2 AM with a test light and a prayer, you know the difference between a factory wiring diagram and some aftermarket color-coded guess. That difference is about 194 pages of DAF-sanctioned schematics, with every splice, connector, and earth point drawn the way it left Eindhoven. The DAF XF105 Wiring Diagram manual on your screen right now isn’t a photocopy of a photocopy – it’s the original OEM document used by dealer techs. No reprints, no third-party redraws. Just the factory stuff.

Running a six-bay shop in San Antonio, I’ve seen guys burn three hours tracing a brake light fault because they trusted a generic diagram. This manual kills that. You get the actual wiring for the ABS-D, EBS-2, EST 42 retarder, AS Tronic transmission – every system on the XF105. And it’s laid out the way DAF intended: main groups, system sections, subdiagrams, and a cross-reference table that tells you exactly which page to flip to when you need the voltage generation circuit (page 01A-1).

Power Supply and Earth: Where the Voltage Lives

Section 01 splits into five subsections: Voltage Generation, Supply Voltage Before Ignition, Supply Voltage After Ignition, Supply Voltage 12 V, and Earth. Each one has its own diagram number (1644405/05 through 1644466/07) so you know you’re looking at the correct revision. The Main Switch diagram (01B-1) includes the battery disconnect logic – critical when you’re diagnosing parasitic draw. If you need charge pressure specs, those aren’t in this wiring manual (that’s a different book), but every power feed and ground path is traced pin‑for‑pin.

CAN Network Topology – Five Buses Mapped

Modern trucks talk over CAN, and the XF105 uses five separate networks: V-CAN1, V-CAN2, I-CAN, D-CAN, and BB-CAN. Section 02 shows the full topology. When you get a “no communication” code on the VIC-2, you can open to page 02A-1 and see exactly which modules are on that bus. The K‑connection topology (02B-1) is also there – not a generic “diagnostic connector” drawing, but the actual pinout DAF uses. That alone saves you from backprobing the wrong terminal.

Engine and Aftertreatment – DMCI and EAS Wiring

The DMCI (Diesel Management Common Rail Injection) diagram in section 03C covers the engine ECU, injector drivers, and sensor inputs. Section 04A gives you the EAS (Emission Aftertreatment System) wiring – everything from the NOx sensors to the DEF doser. If you’ve ever replaced a SCR module on a hunch because the diagram was wrong, you’ll appreciate the factory accuracy here. No guessing what color wire goes to the DPF differential pressure sensor – it’s drawn.

Braking and Retarder – ABS-D, EBS-2, EST 42

Brake system wiring can kill a truck’s uptime fast. Section 05 covers both the ABS-D (Antilock Brake System – Diagnostic) and the EBS-2 (Electronic Braking System). Each has its own subdiagram with component locations and connector views. The EST 42 retarder wiring in section 06 is separate – you can isolate a retarder fault without chasing false positives in the brake circuit. This manual’s organization lets you work one system at a time.

Lighting System – Exterior and Interior (18A, 18B)

Section 18 breaks lighting into driving lights, brake lights, reversing lights, rotating beacon, spotlights, fog lights, marker lights, work lights, stepwell lighting, interior courtesy lights, and visibility lighting. Each one has its own subdiagram. Need to wire a body‑builder accessory? The Bodybuilder Module (BBM) is section 10C, and the reserve wiring is in 16C-7. This manual covers the tailboard preparation wiring (16C-8) as well – a detail that saves you from burning up a $400 multiplex module.

FAQ – Four Questions Techs Ask

Does this wiring diagram cover the DAF XF105 with the PACCAR MX engine?

Yes. The manual is for the XF105 series. The engine system section (03C) includes the DMCI controller used with the MX engine. If your truck has a different engine variant, verify the engine ECU part number against the diagram.

Is the wire color code consistent with European standards?

Yes. DAF uses DIN 72552 color coding. The diagrams list wire colors in text on each line – no need to decode a separate legend.

Can I use this manual to install aftermarket accessories like a backup camera or lift axle controller?

You can use it to find the correct power, ground, and CAN bus connection points. The BBM (Bodybuilder Module) section 10C shows the input/output pins. For anything that touches the OEM multiplex, cross‑check the bodybuilder guidelines linked below first.

Does this manual include torque specs for electrical connections?

No. This is a wiring diagram manual – it shows circuits, not fastener torques. For lug nut or mounting bolt torques, refer to the factory service manual. The focus here is 100% electrical.

Why Factory Source Matters

Aftermarket wiring diagrams are often redrawn from memory or scanned at low resolution. This document is an original DAF PDF, 194 pages, with a proper table of contents and subdiagram index. The file name alone (DAF_XF105_Wiring_Diagram_en-22411001901.pdf) tells you it’s a factory release. I’ve run my shop on these for 28 years – I trust nothing else when a truck’s electrical system needs to be reliable.
