So trying to use the wiring diagram that comes with the manual is a pain in the ass. It is on two different pages and all lines are hard to follow. Compound that with me being bored today and I now present you with the wiring diagram for a naked 03.

Here is a small version



The link to the gigantic version in pdf format is here. You can download it from that link or just use it on the web. Just as a warning, the pdf is huge (2500x1500 px)

Also, I had to use the color Magenta for white. Splices are marked with a Red X. Let me know what you think.

Score! Great timing! I'm doing some rewiring and adding a relay to kill the headlights when the starter button is pressed.

How do I save w/o signing up?

I don't think you can save without signing up. Its free and doesn't take to long. If you don't want to, send me a pm with your email address and I will send it to you direct.

nice work Patrick!
Maybe now I can figure out what wire it was that I tapped into for my driving lights. It was some wire that was marked "SPARE" under the passenger pillion.

Thanks Patric!
It's so much easier to read with color. There is one small error in the ignition switch diagram of this schematic. This error exists in the official Suzuki manual also, but not on all schematic versions.

With ignition switch in the "ON" position:
Diagram shows: (R<->O) and (O/Y<->Br) <-wrong
Should show: (R <-> O <-> O/Y <-> Br) <-correct

In other words, all four wires (R,O,O/Y,Br) should connect together when the switch is in the "ON" position.

Do you have a online link??
It underneath the inline image. Here it is again though. You do have to sign up to download it, which is a bummer, but I don't know of any free image hosting that allows images that big. :(

Thanks Patric!

Thanks! I updated my document to reflect that change.

FYI, although PatrickE already provided a directlink, I signed up using some phoney email address and what not. Just use any basic name you can think of for gmail or AOL accounts, and you're golden.

Ever since the explosion of AOL, I've always been partial to "[email protected]"... I have no idea who has this account, but they sure are getting a lot of junk email :nana:

...Patrick, were you able to confirm that the wire marked "B/O" coming off Ignition Coil #2 joins with the wire "O/W" that comes off the kill switch and starter button and Ignition Coil #1?
The factory manual schematic shows ignition coil wires B/O connected to O/W. Both are constant 12v from the ignition circuit.

Thanks a ton for putting this up.

How similar is this diagram to a 06 SVS? Do you know the differences offhand?

Thanks
Yeah, tbolt did a great job adding color, and thanks PatrickE for posting it up.

You can always do a search to find this stuff, but I think it's good when folks post useful info like this from time to time.

Unfortunately, (or maybe fortunately), engineers are never satisfied with anything, and have to keep modifying the design. There are 14 different versions of the SV650 schematic in the back of the Suzuki Factory Service Manual, Rev August 2008, and this is only the Gen2 manual.

2003 through 2006 schematics are fairly similar. The **** really hit the fan in 2007. Starting in 2007 the the ECU is way different, along with the fuel injection, dual spark, and more EPA emission crap. Even the fuse box got modified. ABS also came in 2007 and added lots more wiring.

On the plus side, lighting and charging system wires and colors are basically the same through the years. With a 2006, unless you really have to dig into the wiring, you're probably OK with this diagram.

Yup, and some of those versions are Euro and other locales also. (That's what the E-# codes in the upper left corner are.)

I sure wish I could get my hands on a copy of that service manual from 08 without paying out the nose. I only have an older one, obviously.

I used the tbolt's diagram this weekend for the autoswitch garage door opener installation. Thanks for the diagram! VERY useful.

Note on the autoswitch opener - easily worth the $30.

flash2pass much better system - with autoswitch you still need to intergrate a remote.
For $30 more you can get a complete flash2pass kit with transmitter/receiver (no need to use remote) and additional $30 for each extra transmitter for other bikes or autos.
I have one full kit plus three extra transmitters to cover my three bikes and one of the cars (no more remote clipped on the visor)
Far superior system to autoswitch in my opinion.
