Volvo Penta S60, S80 Wiring Diagram

Tracing a short on a modern vehicle without the factory wiring diagram is a lost bet. You grab a multimeter, start guessing pinouts, and three hours later you’re still not sure if that ground point is actually a ground. That’s time you don’t get back. This is the actual OEM Electronic Wiring Diagram (EWD) TP3976201 for Volvo Penta S60, S80 Wiring Diagram. 139 pages of factory schematics, component lists, fuse maps, and CAN data. No aftermarket redraws, no missing connector views. What you see is what the dealer uses.

List of Components – What’s Where

Every wiring diagram is useless if you can’t find the part. The manual opens with a detailed list of components broken into four sections. Vehicles with SRS (Airbag)/SIPS bag/IC are covered first, then abbreviations, then how to use the wiring diagrams. Page references are given for every subsystem — no flipping randomly. The component list runs four pages deep, mapping each module to its location in the electrical distribution sections. This is the kind of indexing that saves you from pulling the wrong fuse.

Electrical Distribution and Fuse Maps

Fuse locations are laid out by zone: Engine compartment 11A/1-8, 11B/1-6, 11B/8-23, Passenger compartment 11C/1-7 and 11C/8-13, Battery 11E/1-7. Central Electronic Module (CEM) fuses are split into F1:F16 and F1:F34. Rear Electronic Module (REM) fuses F1:F19 and F20:F38. Relays are grouped by function — ignition switch, engine compartment FMA2 – FST3, and other relays. If you need to know which fuse feeds the auxiliary light in an S80, it’s right there. No chasing diagrams after a blown fuse.

Control Modules and CAN Data Communication

Modern electrical systems live on the CAN bus. This manual documents both high-speed and low-speed CAN data communication, plus LIN data communication. Control module locations are mapped with overviews of designations. Central Electronic Module (CEM) and Rear Electronic Module (REM) each have their own two-page spreads. The Accessory Electronic Module (AEM) is covered separately. If you’re diagnosing a no-start that’s actually a CAN bus fault, you need the termination resistors and node addresses. That data is in these pages.

Group 35 Lighting Systems

Lighting wiring is model-specific. The manual separates high and low beam for S60 and S80, including Bi-Xenon and daytime running lights. Fog lights, brake lights, reversing lights, home safe lighting, position/parking lights, tail lights, license plate lighting, interior lighting, beam length adjustment, and auxiliary light — each gets its own schematic. No generic “insert bulb here” diagram. You get the actual wire colors, connector pinouts, and ground paths for your specific Volvo Penta model.

Group 36 Additional Electrical Equipment

Beyond lighting, the manual dives into rain sensor, direction indicators, wiper/washer (windshield and headlights), high-pressure headlight washer, horn, electronic immobilizer, anti-theft alarm, parking assistance, and the Accessory Electronic Module (AEM). Every subsystem is broken out with its own page. Need to trace the towbar cable harness? 7-pin and 13-pin versions are both diagrammed. The 12V outlet in the cargo compartment is separate from the front outlet. That level of detail keeps you from splicing into the wrong circuit.

Source Authenticity – Why This Is Not Aftermarket

I’ve watched techs waste an hour aligning wire colors from a $20 aftermarket manual that shows a 2005 harness for a 2008 model. This is the actual Volvo Penta OEM file, numbered TP3976201, with the original VolvoTechInfo bookmarks. The manufacturer data, component lists, and wiring paths are taken from the factory release. No third-party reinterpretation. If you need to trust a wire color, you trust this document.

Frequently Asked Questions

Does this manual cover the 5-cylinder gasoline engine?

Yes. The engine management system for 5-cyl (both turbo and non-turbo) is included, with separate schematics for each variant. The 6-cyl and Bi-Fuel versions are also covered.

What about the diesel engine?

Diesel engine management is on page 2 of the list of components. The manual includes a dedicated section for the diesel EMS.

Are torque specs included in this wiring diagram?

No. This is a wiring diagram, not a service manual. It contains no torque values or repair procedures. For mechanical repairs you need the corresponding factory service manual.

Can I use this for both S60 and S80 models?

Yes. The manual covers both models, with separate schematics where wiring differs (e.g., high/low beam lighting, tail lights). Always verify the model-specific section before cutting wires.

If you’ve read this far, you already know the value of having the real thing on your bench. Don’t waste money on condensed aftermarket junk that leaves out ground locations. Access the Factory Manual – the actual OEM file – and keep it on your tablet or printed out. 139 pages of schematics that match what the dealer pulls up. That’s the difference between guessing and knowing.
