Volvo Penta S60, S60R 2007 Wiring Diagram – Factory OEM

If you are reaching for a wiring diagram for a 2007 Volvo Penta S60 or S60R, you need the factory document, not some aftermarket reprint that guesses at pinouts. I have seen too many guys chase electrical ghosts because someone handed them a generic schematic that didn’t match the CEM or REM modules. This is the real deal – TP 3997202, published by Volvo Car Corporation in 2007, covering all S60 and S60R variants with the SRS (Airbag), SIPS bag, and IC (Inflatable curtain) systems.

All 225 pages are built around the factory wiring harness, ground points, fuse blocks, and control modules. No condensed “simplified” diagrams. Every circuit is shown as Volvo engineered it. That means you get the exact pin numbers, wire colors, and connector views that match what is under the dash and hood of the car you are working on. If you have ever tried to trace an intermittent airbag warning light using a third-party diagram, you know the frustration. This manual kills that guesswork cold.

SRS/Airbag Warning – Page 2

Before you even think about poking a multimeter into the wiring, read the warning on page 2. It is not boilerplate. The manual states that working on vehicles equipped with SRS/SIPS bag/IC requires extra caution to avoid personal injury or system damage. Those explosive seat belt tensioners and side airbags can deploy if you short a wire or ground the wrong circuit. The document tells you exactly how to recognize which system is installed – look for “SRS” on the steering wheel and above the glovebox. It also lists general recommendations: do not pinched wires, avoid fitting accessories near sensors, and follow the SRS section in VIDA for steering gear work. I take this section seriously, and you should too.

Electrical Distribution Overview – How the Power Flows

The Overview section (starting at page 8) gives you the big picture of electrical distribution. Two sheets cover how power comes from the battery through the alternator, splits into the engine compartment fuse boxes (11A, 11B), passenger compartment fuse panel (11C), and the battery-mounted fuses (11E-11L). Every fuse location is listed with its amperage and circuit assignment – for example, the central electronic module (CEM) has F1 through F34, and the rear electronic module (REM) has F1-F13 and F17-F38. You need this when a cabin light fuse keeps blowing and you find it is the REM that is drawing. No other manual maps out the REM fuses that way.

Group 23 – Engine Management System: 5-Cyl. Turbo Schematics

The fuel system group (Group 23) covers all engine variants: naturally aspirated 5-cyl., turbo, Bi-Fuel, and diesel. For the S60R turbo, you get two full sheets of the engine management wiring, including the ECM pinouts, fuel injector circuits, and oxygen sensor signals. The wiring for the emission control system – both NA and turbo – is separate, so you don’t have to wade through irrelevant pages. If you are diagnosing a no-start on a 2007 S60R, start with the engine management sheet and check the main relay supply from the CEM. Page numbers in this group run from about 40 onward, but you should use the Table of Contents on page 3 to find the exact sheet for your engine code.

Fuse, Relay, and Ground Connections – Real-World Diagnostics

I have seen more than one tech spend an hour trying to find a parasitic draw because they assumed the ground points were in the same place as a 2005 model. This manual lists every ground connection from 31/1 to 31/120, with location descriptions. Same for relays: ignition switch relays, engine compartment relays (FMA1 to FST3), and “other relays” in the cargo area. The Auxiliary Lights section (Group 35) even includes the wiring for aftermarket light kits – something the dealer usually keeps to themselves. When you are wiring up a set of driving lights on an S60, you want the factory relay location so you don’t overload the CEM output.

3 Reasons to Use OEM Documentation Over Aftermarket

First, accuracy. The aftermarket wiring diagrams I have seen for this generation S60 often merge the REM and CEM pins or skip the LIN data communication nets. This manual includes two full pages on LIN communication – the low-speed bus that runs the seat memory and climate control. Second, the factory document is updated for changes up to April 2006 (as stated on page 2). Third, it comes with the official Volvo order number TP 3997202, which replaces the previous electronic wiring diagram TP 39101001. That traceability matters when you are billing a customer and the repair needs to pass a dealer inspection.

Who Needs This Wiring Diagram?

If you are a home garage mechanic pulling a 2007 Volvo Penta S60 or S60R into your driveway, this is the only wiring reference you should trust. The step-by-step instructions in the “How to use the wiring diagrams” section (pages 6-7) walk you through reading the connector diagrams, understanding the abbreviations (like CEM, REM, AEM, BCM), and interpreting the splice numbers. Beginners often panic when they see a sheet full of lines – this manual tells you exactly how to follow it. For professional techs, the grounded component warnings and SRS disable procedures alone are worth the access. You cannot afford to guess on airbag wiring.

Does this cover the S60R bi-xenon headlight wiring?

Yes. Group 35 Lighting includes high and low beam (Bi-Xenon) & daytime running lights, plus active headlights (ABL). The diagram shows the headlight control module, the leveling motors, and the DRL relay.

I need to trace a short in the power seat circuit. Where do I start?

Group 85 Interior equipment covers power driver’s seat and power passenger seat separately. Look for the AEM (Accessory Electronic Module) sheets in Group 36 – the seat memory module connects to the low-speed CAN bus. Check the ground point 31/67 under the driver seat, and verify the 12V supply from the passenger compartment fuse F19 (15A). If the fuse is fine, the wiring diagram will show you the connector C1 pin 9 – that’s the brown/white wire for seat movement. Start there.

Don’t waste time with aftermarket diagrams that can’t tell you which fuse feeds the ionizer or where the diesel glow plug relay lives. This factory PDF gives you the complete electrical system for the 2007 Volvo Penta S60 and S60R in one file. Access the Factory Manual from AutoRepairManuals and keep it on your tablet next to the scan tool. You will refer to it every time you work on these cars – I guarantee it.
