Iveco DAILY 2007 Technical Manual – Factory Bodybuilder Instructions

If you’re planning to modify an Iveco DAILY from 2007, you need the factory spec sheet, not some aftermarket reprint. I’ve seen too many hacked-up vans where a tech used a generic manual and guessed on torque. That’s how you snap bolts in a frame rail or fry a fuse box. The Iveco DAILY 2007 Technical Manual is 132 pages of the exact data Iveco sent to body builders. It tells you what you can cut, what you can drill, and what you absolutely cannot touch. Aftermarket documentation? I don’t trust it for this. IVECO explicitly states that any modification not covered in this publication voids the warranty. That alone makes this manual worth having.

7 Sections Covering Electrical, PTO, and Chassis Modifications

This manual breaks the DAILY into seven main areas. Section 2 covers the under-dashboard and engine compartment relay fuse boxes – pages 83 through 91 show you which fuse does what for both Euro4 Diesel and CNG models. Section 4 goes into PTO installation for manual and automatic gearboxes. Need to add a power take-off for a hydraulic pump? The factory procedure is right there, with specific torque values for the gearbox adapter. The update table on page 3 lists every revision, including a note about tyre screw tightening added on page 54. That’s the level of detail you get: a living document with field corrections.

Body Builder Instructions: What You Are Authorized to Modify

Page 5 of the manual spells it out: any change not authorized in writing by IVECO makes the guarantee null and void. So if you’re building a camper or a service body, you need to know exactly which crossmembers you can drill and which load-bearing structures must remain untouched. This manual includes the frame rail drilling templates and reinforcement requirements. It’s not a suggestion – it’s the legal boundary. The manual also covers the CNG variant, which has its own fuse box layout and PTO options. Don’t guess which lines you can tap; the factory diagram is the only safe reference.

Does This Manual Cover the Fuel System?

Not in the sense of a full fuel injection diagnostic. This is a bodybuilder guide, so it focuses on the systems you might tap into for a modification: electrical power distribution, PTO hydraulic connections, and exhaust routing for CNG. If you need a complete engine overhaul manual, look at the IVECO DAILY Repair Manual which covers the F1A and F1C engines in depth. But for anything involving chassis alterations, auxiliary equipment installation, or wiring add-ons, this technical manual is what you need. The publication number is 603.93.751 – Iveco’s own part number, not a third-party rehash.

3 Reasons You Want OEM Documentation Over Aftermarket

First, torque accuracy. Page 54 has the tyre screw torque table – Iveco specifies the exact Nm value for each wheel stud. Aftermarket manuals often state a generic range like “80-100 Nm” which leads to under- or over-tightening. Second, wiring diagrams. The relay locations in the engine compartment are different between diesel and CNG. Only the factory manual shows those pinouts correctly. Third, liability. If you modify a vehicle for a customer and something fails, the OEM documentation is your defense. The IVECO Daily 2007 Bodybuilder Instructions is the only document that Iveco recognizes. I’ve had to tell shop owners more than once: throw out the Chilton and buy the factory book.

Understand the Wiring Before You Touch It

The fuse box pages (83–91) are worth the price alone. You get the under-dashboard relay fuse box layout, the engine compartment relay fuse box for Euro4 Diesel, the optional engine compartment fuse box (t.2.28/2.29), and the CNG-specific box. Each relay is identified by function – no abbreviations like “ACC” that could mean anything. The manual also includes the trailer kit removal notes (page 95) and a new paragraph 2.16.9 added in July 2007 for a specific update. If you’re splicing into the electrical system for a rear camera, auxiliary lights, or a lift gate, this is the only safe wiring map.

PTO Installation: Factory Procedure for Manual and Automatic

Section 4 adds PTO instructions for Daily CNG with manual gearbox (page 12) and automatic transmission (page 13). The specific procedures on pages 18 and 19 tell you which gearbox housing to use, the correct gasket thickness, and the bolt torque sequence. For the Manual Transmission, you also need the gearbox fluid capacity – that’s in the appendix. Aftermarket guides often skip the PTO because it’s vehicle-specific. This manual doesn’t. Whether you’re running a dump body hydraulic pump or a compressor, the PTO installation steps are documented with factory callouts. The Iveco STRALIS 2004 Technical Manual – OEM F3A Engine Guide follows the same philosophy: get the factory specs or waste time redoing work.

Frequently Asked Questions

Is this manual for all DAILY variants?

Covers the 2007 DAILY light range, including Euro4 Diesel and CNG models.

Does it include torque specifications?

Yes. Page 54 has the tire screw torque table. The manual also covers frame bolt torque, engine mount specs, and fuse box mounting torque. For the PTO installation, specific torque values are given for the gearbox adapter. Aftermarket manuals often omit these, leading to stripped threads or failures. This factory manual ensures you have the correct values for every fastener mentioned. The Manual Transmission section includes the torque for the bell housing bolts – something I’ve seen snapped more than once because someone used a generic spec.

Can I use this for a camper van conversion?

That’s what it’s for. Bodybuilder instructions tell you which crossmembers you can cut, where to drill, and what reinforcements are needed.

What about electrical wiring diagrams?

Pages 83–91 show relay and fuse box layouts for diesel and CNG. Under-dashboard and engine compartment boxes are both documented.

This is the manual Iveco designed for anyone who cuts, welds, or wires a DAILY. It’s 132 pages of factory-verified data. Aftermarket copies leave out the critical torque values and update notes. Don’t risk a warranty void or a safety failure on a modified vehicle. Access the Factory Manual and keep it on the bench next to your torque wrench.
