I have read through the various electrical threads, and I'd like to make certain my understanding is correct. If you could verify I have it right, or tell me what I have wrong, I'd appreciate it. I will get a manual pretty soon.

The 2 unused, 2 pin connectors under the right side on a '14 non ES are for grip heaters. As I understand it the OEM grip heaters are plug and play, and when the system senses they are there, a new menu will be available on the display to allow me to control them.

The 3 pin connector under the Rt cowl contains one switched power lead, one unswitched power lead and a ground. This connector was origonally intended for OEM aux lights. Were those lights on all the time? I don't understand what controlled them and why they would have both switched and unswitched power.

The four pin connector under the rt. cowl is a diagnostic connector.

What is the 4 pin connector under the seat for? Heated seat?

Thanks, any clarification will be greatly appreciated.

I can't speak to all of the connectors, since I had a Gen 1, but here is what I remember:

The 4-pin connector under the right fairing (clustered with the 3-pin) was for the factory heated grip kit on the Gen 1 bike. It wasn't removed for the Gen 2.

The 4-pin connector under the seat is a diagnostic connector.

The 3-pin connector has both switched and unswitched power for the relay that comes with the factory aux light kit. The switched circuit is controlled by the key, so the lights would always be on while the bike is running. Many owners use this connector to control an aux fuse block for additional electrical items.

Thanks. It doesn't seem to make much sense to put a switched and an unswitched wire in a connector for lights that are activated with the key, but I'm no engineer. I haven't seen a pinout that i can think of for the 4 pin connector under the right cowl. I guess I need to get a manual and a wiring diagram.

I stashed this away after finding it in one of the other aux light threads...

"Blue/black wire goes to the "signaling system" fuse (brake lights and horn) and has power with the key in the 'on' position. Black/green wire goes to the headlight fuse and is energized when the headlights are on. Light green/white wire goes to the ECU. Black is ground (duh!). Looks like Yamaha intended the grips to share loads with other items, because they typically draw only about 2.5A. heated gear would easily be double to triple that load."

Thanks for the info. That seems like an unusual combination. As I've worked on things by different manufacturers, I've learned that all of them have their idiosyncrasies, particularly when it comes to electrical. If you work on them long enough, you kinda start to understand how the engineer that designed it thinks. I haven't worked on a Yamaha since my '82. It may take me a while to see why they were doing things the way they did.

Unknown / unconfirmed :
4-pin Female Aux connector:
Black/White stripe = Ground
Red / Blue stripe = 12V Always ON (Fuse?)
Blue/ Black stripe = ?? Seems off, then around 3-4V with ignition? (but my DMM is jacked so I don't trust that)
Blue/ Red stripe = ?? Seems off, then around 3-4V with ignition? (but my DMM is jacked so I don't trust that)
I have confirmed this information manually and checked it against the wiring diagram also. The plug is number 43 on the non ES drawing and number 44 on the ES drawing. I hate it when they use different identifiers on different drawings. The Red/Green which you have labeled as Red/blue goes to the 7.5 amp "backup" fuse which is listed as item 20 on both drawings and it is always hot. A branch of this circuit (Red/green wire) goes to the instrument cluster. I measure the other 2 wires at 2.5 volts and they both go into the instrument cluster as well. They are both switched. Since we do not now what these wires do in the cluster I would recommend against using any of them for any other purpose and simply leave it as a test connector as intended.

4-pin Male Connector - Under Seat:
Black = ??
Light Blue = ??
Light Green = ??
White / Red stripe = ??
I have confirmed this one as well. It is the ABS test coupler and is either number 57 on the Non ES or number 66 on the ES drawing. The Black is ground. The others are all switched. I read 10.5 Volts at the Blue wire and 2.5 at each of the others. Again, I would not use this for anything other than it's intended purpose as a test connection. FWIW, the Light Blue wire is shown here is also shown to be Light Blue on the drawing, but on my 2014 NON ES bike it is Light Blue/Green

Confirmed All Models
3-pin Female Aux connector (A.K.A. Aux Light Plug):
Black = Ground
Red / White stripe = 12V always on with 20A fuse
Brown = 12V on when ignition is on with 20A fuse
see = http://www.yamahasupertenere.com/index.php?topic=12961.msg206771#msg206771
I had wondered why the engineer would provide a 20A switched as well as a 20A unswitched power wire for the aux lights. After looking at the drawing, I believe that they intended the Brown wire to be a trigger wire for a relay just as AVGeek said. The switched wire is a smaller gauge wire and is on the Ignition circuit fuse (number 7 on both drawings) which of course has a lot of critical stuff on it. That particular terminal is not able to supply 20A, the whole circuit is. I wouldn't recommend the switched wire for anything but a trigger wire as seems to be intended. Most of the recommendations here are along that line, but I have heard people at events talking about putting a light on the switched side. Not recommended. The Red/White wire should support anything that an always hot 20A circuit could be used for. There is nothing else on that circuit at all. That fuse is labeled O/P on my 2014 Non ES Bike and is Item 4 on both drawings. On the drawings it is called the "Accessory light fuse (OPTION)".

Anybody dig up more info on the legacy grip heater plug? I can't seem to find it in my 2016 FSM.

Also yes I'm sure Yamaha intended the brown wire in the aux light connector to be a trigger for a relay with relay power delivered from the dedicated 20A outlet. I've got a plan for my electrical accessories setup, I'll be dropping it in a dedicated thread when I've got it done. But the lights connector will be most of my power source (nothing particularly high load) with the brown wire being the trigger for my ignition power circuit.

So where can you get a bare female connector for the 3wire plug. I want to connect a dual usb plug on the left side of the dash?
http://www.cycleterminal.com/mt-series-090.html about midway down the page "3 pin MT .090 - 2.3mm Male and Female locking connector " appears to be it. I haven't ordered yet as I'm still planning the details of my wiring job.

I've ordered from this place a couple times in the past. Good resource.

Edit: After I've done my modifications I'll link them here to share.

Well im not finding this 3 wire plug for accessories use on this 17 non es. Found a 4 wire under the seat.
Mine was tucked in behind the loom roughly straight down from the rubber grometted hole. Initially I, too, was unable to see it.

You will find two white connectors, the three contact (auxiliary lights) and four (legacy heated grips). They have dust covers over them.

Cover off of the aux. light connector.

And last these are the new grip heater wires. Interestingly they do not put dust covers on them. They are located right up front under the cowl.

I ordered a bunch of connectors last night. Hopefully I'll get them soon and can start (and finish!) my wiring project.

Ah that was my next question what the grey and black plugs were for. I’ll dig a little deeper in the loom.

FYI I just went through the manual and am showing the four pin as the connector for the Yamaha Diagnostics Tool (which is $500 but I ultimately want!), not a legacy grip warmer. The wiring colors do not match the gen1 grip warmer circuit.

The wire routing diagram actually shows two different connectors, this one and one tucked behind a loom that I was unable to find. The manual wiring diagram shows a connector at the lean sensor that has the same wire colors as this four-pin connector and calls the Yamaha Diagnostics Connector as a three-pin connector with a different layout (and wire colors) as the accessory lights.

142-1.jpg

The red circle is the four pin connector and the blue circle is the one I was unable to find. It is right around a single wire connector (connected) so perhaps that's it. I'd like to pick up a Yamaha Diagnostics Tool one day, if I do I'll make sure to find everything :)



On another note I can confirm that if you buy the OEM Gen 2 grip heaters all you need to do is plug them in and they will work, the menu structure will show them like they do the ES models. I found them on eBay for $359. I'll outline the installation at a later date in a separate thread (I have not installed them yet, I'm just kinda an impatient kid sometimes and had to open the box, plug them in, and check them out.

Shipping charges on these connectors is a joke!
What a bunch of bullshit!
It's tough to write a web cart that actually does shipping costs well, especially with small items. I'm pretty sure that's the case with cycle terminal. You could find the connectors on Digikey or Mouser, most likely, although it may be a bit tougher to find. As larger store they may get you a better shipping setup but I'm not sure you'd be able to buy the connectors singularly, you may have to buy in a minimum quantity.

Edit: I wasn't all that offended by the shipping charges on my most recent order but I ordered more than that. I've got a project a'brewin!
