Many thanks for the wiring diagram. It's amazing!

One point of clarification though. I'm not sure if your 2013 S differs from my 2016 FXS, but I don't have any USB connections on my ODBII port. Pins 8 and 9 are actually a 3.3V serial UART running at 38400bps (also seen here: http://electricmotorcycleforum.com/boards/index.php?topic=4296.msg28366#msg28366)

So I'm not sure if the USB label in the wiring diagram is a mistake or whether you actually do have USB on your bike. The labeling of TX and RX suggests it's probably a UART (USB would be labeled as D+ and D-) Are you able to clarify?

[togo]

I think those are the USB D+ and D- *signals*, not actual connector. 

When I've opened up USB cables, I've found red and black, which are +5V and ground respectively, and a differential pair. All four seem to correspond to wires indicated on Burton's diagram.   I haven't tested this, but I imagine the USB cable or bluetooth dongle the dealers use isn't much more than a tap into these particular pins, exposing a fairly standard USB-Serial interface.  I bet it'd show up as /dev/ttyUSB0 in Linux.

[rDacted]

Yep, that's exactly what I thought when I read the diagram - so I built a cable to do exactly that and it didn't work.

Then noticing the post I linked to in my previous post I decided to look at the signals using my scope - and sure enough I discovered that it was a 3.3V serial UART as the post I linked to suggested. So I built a cable to decode the UART and it was correct.

I'm 100% certain that I've got it correct on my bike. My question was whether this was different for the 2013 S - which is what the wiring diagram was made against. I suspect that Zero wouldn't change their pinouts, so I suspect Burton might have it labeled incorrectly - but I'm not certain which is why I posed the question.

I'm happy to stand corrected for the 2013 model - but I wanted to make sure that new players don't waste time building a cable if it won't work for them. If you've got a spare moment, please check yours out with a scope monitoring pin 8. If you turn the bike on while the scope is connected I think you'll see serial data being sent as the board starts up. In fact, it should resemble this:

For what it's worth, the digiNow reaper dongle works against both my 2013 DS and 2016 DSR. So, either the dongle is really adaptable to the signal pin reassignment, or there's something else going on here.

[rDacted]

That's interesting. Do you get the same output from the reaper dongle as I posted earlier? Or does it only do the CAN/ODB2 interface? I tried to buy one but Hollywood electrics are currently out of stock.

The dongle accesses the MBB console, and not the CAN itself.

[skyrapper]

Also for MY13 you can use a USB-UART converter to communicate with the MBB.

I followed the same thread that rDacted mentioned (http://electricmotorcycleforum.com/boards/index.php?topic=4296.0) for building an adapter for my Zero 2013 S and it works.

Sorry for my delayed response, I have changed all my content posts to notify me of new replies!

From the post skyrapper linked

2. Solder the wires to the pins on the OBDII connector as follows:
- black wire to pin 5
- white wire (RX) to pin 8
- green wire (TX) to pin 9

If you look at my ODB in my wire diagram the pins are appropriately labeled.
Pin 5 (orange black stripe) as GND
Pin 8 (Red black stripe) as RX
Pin 9 (Gray black stripe) as TX

That said I highly recommend the use of the diginow dongle if you ride a lot with a bluetooth enabled laptop like I do (to work every week day) as it is so quick to use when you have issues. Note this will only gain you access to CAN traffic / MBB settings and will not let you reprogram your controller. You need a DB9 serial port to USB plus software on top of this to access everything through just the ODBII if I recall.

[rDacted]

Awesome, thanks.

Could I make a recommendation that you remove the word 'USB' from those diagrams? They've confused me, and it seems others as well. I'd recommend 3.3v UART, or 3.3v serial. (not to be confused with RS232 serial which has much wider voltage swings and could damage things)

For reference I'm talking about the wiring diagrams here:
http://electricmotorcycleforum.com/boards/index.php?topic=3603.msg20961#msg20961
and

Again, thanks for the wiring diagram. It's quite useful!

When I get a chance I will update the labeling of the "USB" which references the USB to UART connector required to interface with the bike via the ODBII

Anyone else have changes which are suggested I can make at the same time?

perhaps a note that the fuse order may be reversed as seen here: http://electricmotorcycleforum.com/boards/index.php?topic=6004.msg45246#msg45246

[Burton]

Different fuse box. The 2013 has 4 fuses not 6

If someone wants to attach a picture of the input / output side for a 2013 S  / DS fuse box we can see if this is indeed the case.

Long time no see

I had some time today and since I will be adding a DigiNow SC2 to my bike soon I had to make sure the "Aux port is being used to charge" feature was "added" to my bike. So I tried to confirm with Electric Cowboy that the Trikester mod was required and found the diagram was wrong >__<

Updated the diagram and tried to include all requested changes in the process.

Please review and provide feedback if something isn't accurate or the quality is lacking.

EDIT (04-23-2017) v1.3.0

• Changed blue underlined references to USB to either 3.3v UART or UART (in the case of the unused red wire) | rDacted
• Corrected the Aux "charging" indicator wires coming from the SBS75X pins 3 / 4 to indicate they connect to a siliconed female connector on the battery next to the B+ / Bi wires. (see attached image of connection point) | Electric Cowboy
• Updated pin 38 / 40 wires coming from MBB used by Trikester to let the bike know to accept AUX charging to include the switched 100K ohm resistor circuit and a note about why it exists. This is NOT a stock circuit on 2013 wire looms. | Electric Cowboy
• Updated Fuse box section to better reflect reality and changed the AUX circuit to stock amp size (10amps) from 30amps. This update propagated out to the wire labels where fuses are referenced. (see attached image for fuse box sticker) | MrDude_1
• Updated credit to include link to my signature link showing all content found here on EMF, which includes this post, from my personal website. | Burton

Excellent! I'll get these details on the wiki and link the new file.
