I have four things I wired into the bike to get it ready for getting Lost, first would be the GPS. BMW did indeed include the factory GPS plug, zip tied to the frame under the tank under the left side.
Since I don't run a BMW rebranded Garmin unit I just cut the plug and soldered a standard SAE plug that I have on all our bikes so I can move things around easily.

Here's the OEM GPS plug and the finished product, mine just tucks away after making the connection behind the steering head. It's switched on with the ignition and no fuses needed! Thank you CANBUS.

I mounted the Garmin Montana 600 using a

, with a 1" RAM arm, putting it centered and not obstructing the view of the gauges. All removable in 1 minute for days I don't need the GPS.

Next up is power for my HPRC hard case on the tail. I removed the BMW accessory outlet, cut the plug off and ran some new wire to the back to another SAE plug which plugs into a panel mount SAE receptacle on my box. Again, switched and fused thanks to BMW.

Here you can see the SAE plug coming from the accessory circuit.

Next up, Gerbings variable heat controller.
This one I wired directly into the battery using the Gerbings harness which has an inline fuse. I routed the harness so the fuse is hanging down in between the battery and the shock to give me access without taking the tank off.
I mounted the controller to the bracket that was used for the BMW outlet, seems to be a good out of the way yet easily reachable position for it. It's attached with 3M Dual lock.

The lead going into the jacket lives in between the tank and seat and can be pulled up when needed.

And finally I installed a standard SAE plug going directly to the battery for charging or jumping the battery ( we carry a 6' SAE to SAE wire with us to jump start if needed). It's also for my Slime Top Up mini air compressor which has a SAE plug soldered on it. (seeing a pattern here?).
I have the tail hanging down on the left side frame, zip tied in place.

I think that's about it for now, so what are YOU going to wire up to your bike.

 

BMW did indeed include the factory GPS plug,

Hi Lost Rider, could you please clarify a couple of things for me.
I spoke to my BMW mechanic about this power outlet.
He scoured all of his literature and advised the following;

• He is not aware of this plug
• The schematics only show one accessories outlet, but doesn't differentiate this GPS one from the socket mounted on the LHS
• He says the one shown on the diagram is only rated at 5v
• The wiring colours shown are not the ones he remembers on earlier GPS plugs (GS bikes?)
• He said there was a problem on previous bikes where the power outlet did not automatically shut down after a few minutes; only until the battery was almost drained!
• The current BMW Garmin units use the automotive lighter socket style plug, not a 'hardwired' plug like you have shown
• I did want to get a compatible male plug for this outlet so I could keep the wiring stock (I can change to SAE connectors if required)
• He has known BMW to change items between models and not provide sufficient technical detail

I will be mounting a standard Garmin GPS. It has the lighter socket on the end of the lead, I will change this so I can wire directly in to a controlled outlet such as the one you have shown.


Thanks for your help on this.

 

Since Thursday you've ridden 600 miles, hung out with an out of work comedian, met up with two members from the forum, performed your 600 mile service, installed multiple luggage configurations for demonstration purposes, wired a GPS, heated clothing connection and controller, USB recharging connection and a multi-function electrical connection, taken photos of all of it and posted it all here.

Get busy man. Life is short. Don't want to waste it.

 

This is why Joe is such a great resource. Nice trailblazing and sharing, as usual.

 

Hey Finn, great post and it was great meeting you and Bonkorama at the Rockstore!
Let's make sure to schedule a ride soon. I just finished my 600 miles today and will schedule the first service with my dealer tomorrow.

As for the electrics... First off, thanks for showing BMW's GPS connector, I had no idea this exists.
I went a slightly simpler route in that I wired Garmin's fused harness directly to the battery for my zümo 550 and another SAE connector also directly to the battery (fused as well). As I use my GPS mainly as my on-board stereo, I also routed a shielded headphone cable extension from the GPS to a location closer to the seat to plug in my headphones.

I am using the wireless HeatTroller for my Gerbing heated gear and I plug the jacket via round-to-SAE adapter into that pigtail. Less cables, cleaner bike was my goal so I did not add the additional cable for the Gerbing harness.

 

I have a four button BMW mount coming that I hope will plug into the socket you mention. If not, will plug it into my PDM 60 that I will install. Removing the tank reminds me of my C which required the same. Any particular hints on removing the tank?

 

Thanks for the tank off steps. I could get to the battery terminal by just tilting the rear of the tank up after removing the rear bolts and loosening the front bolts. Just wanted to attach a ground wire.

Have the Rizoma universal plate holder and aftermarket LED turn signals done. Break time is over so I will now do the P3 lights, ledrider driving lights to a second Skene controller, direct to battery powerlet plug, flash to pass garage door opener and the rear hugger. The only advantage to the miserable continuation of winter; time to tinker without missing out on riding.

 

Battery Charger Advice & Accessory Socket Type?

So I'm leaping 42y into the future from a 1972 R75/5 to a nineT and I need to buy a CAN-BUS friendly battery charger.
BMW's chargers are priced a bit high for my taste - so I'm looking at a TecMate TM-141DUAL Optimate 4DUAL unit. If I don't attach their pigtail, I'll need an extra lead/plug to plug it into the nineT's accessory socket. Can anyone tell me whether this is an SAE-79 socket or an SAE-72??
Thanks Guys.

Pigtail fit direct to the battery
Just purchase the optimate 4 dual and connect the positive wire (red) with an eye fitted on the cable if it has one onto the positive jump starting pole on the left under the front seat on the plastic crossmember near the tank ,then the (black) negative wire again with an eye fitted under the bolt retainer clamp on the frame as it steel and not alloy ,to the middle bolt of the alloy finished seat holder and your all done ,and if you fit the optimate lead this way it will directly charge you battery without disturbing the can bus without any damage ,and you can also run an adapter off the battery pigtail to run other items on the fly through the lead extra adapters available from optimate .
If you don't understand I can post some piccies pointing out the contact points

 

Thanks for the kind offer Finn. Let me see what shows up from Amazon before I bug you for a plug. I believe SAE-79 is BMW's standard socket for all bikes from 2004 onward. If it is, then I'll have the option of attaching the Optimate pigtail, or plugging into the accessory socket. The Optimate 4DUAL has a CAN-BUS charging program.

 

Here's where I attached my pig tail end to the frame for easy plug in / remove

 

I put a powerlet socket direct to battery terminals ( hot lead fused) on every bike I have had so that I would not have to worry about the bike's system. I did the same for the 9. I like having the extra socket as it can easily accessed and used for anything that takes a powerlet plug.

An interesting thing about this bike. I had a PDM 60 programmed ready it install with driving lights and I put on the lights and felt the bike didn't look good with them on so I have the PDM on standby in case I change my mind. Quite a change from my GTL where I have every doo dad you can get. Different bikes stir different vibes.

I am confident that this winter will end before the next one starts. When I first moved to this area I was told there are 2 seasons, winter and a short period of time to get ready for the next winter. This year it feels like that.

 

im dumb. please help.

for my heated vest, i attach the positive wire from the vest harness to the battery bolt directly beneath the + symbol shown on the plastic cover (which is the positive battery terminal) yes? where does the negative (other wire from the vest harness) go? on the adjacent bolt? (is that the negative battery terminal?) or somewhere else?

feel dumb for asking but i have no clue.

 

Post 16 and the right hand pen should help with your dilemma GusTSR do not connect your harness to both red terminals

 

thanks bose. i'll fix it

i did in fact connect to both red. what damage did i cause…?

 

Lesson time: in post 16, you're pointing to the positive terminal of what? That's not the battery, right? What are those two red terminals (the one with the + sign on the plastic cover). I'm quite lost.

I'm trying to find the battery terminals to wire a harness (is that an SAE? Right term?)

How do I get to battery terminals?

 

That is a jump start access port, the battery is under the tank. Same thing really, but you can't get to the negative on the battery. You could ground your harness somewhere else, but if you don't know exactly where to go then you could have issues.
Getting at the battery isn't too difficult, and figuring it out gives you knowledge about your bike.

Look at Post #8 for instructions to remove or just lift up the tank to get to the battery, it's all there. Also, like I mentioned in the beginning of the thread, it's wise to put your harness fuse in a place where it can be changed without removing the seat or tank.

It's pretty straightforward once you remove a few bolts, let us know if you need any more help!

Good luck.

 

Thanks Lost rider,

guess i got spoiled with my bonneville and how easy it was to hook up a harness to it…..the 9T has many more secrets… i will go over your detailed instructions and see if it's something i can try on my own...

before i commence my adventure to discover the battery though, perhaps you can tell me if that plug on the left side of the bike (below the tank) is actually a usable plug? I heard it was a GPS plug: if so, and if i get the nav V unit, will i just be able to plug the gps into that plug or do i have to go through another process of attaching a harness to the battery?

thanks in advance.

 

where to get power

I need to pull switched power from the front of the bike for my relay and aux lights. I know I have to run a hot off the battery / probably off the pos bar behide the tank. Pehaps somewhere else if I get an idea. But also need switched power. I plan to put my relay somewhere around the horn area. So, where to get power and switched power?

Ideas?

 

Can't you tap off the headlight for your switch to the relay?

 

Just hooked up a nifty weather proof USB charger thanks to advice on hear. I had my neg on neg terminal next to charging point also. Couldn't understand why it wouldn't work. I've now mounted it just below left to key. I have a really clever I phone clip which is mounted to centre of bars. I put in a double USB charger so now I have my phone charging on bars and iPad in tank bag also on charge for any bigger trips. Would post pics but for some reason can't from iPad ?

 

I purchased this hard wire connection for my garmin gps

Garmin USB Power Cable

I am not sure if I should run it all the way to battery (will it stay on and drain battery ???) or should I connect it to the plug under the tank. Not sure which plug is it and do I have to take the tank of to complete.
Thanks
Krys

It's mentioned in another thread (GPS?) but accessible from the left under a zip tie. For the Nav V you just take off the cap and install it. No tank removal necessary at all. Easy to do and works without any intervention (ie programming).

 

The wire I received comes with a inline fuse, and a red and black wire.
The oem plug has a brown and red/white wires. How would those connect and can I take out the fuse since its at the end of a long wire.

Thanks

 

no fuse needed, wiring is correct.

 

thanks Krys

 

For anyone wiring something to the R9T, the screws to the left and right of the positive connection bolts, right behind the tank and under the front of the front seat are screwed into the frame and easy to use as negative connections. You can slide the terminal/crimp/wire under the black plastic seat brackets.

 

Can anyone tell me the purpose of the big fat circular socket with a screw-on cover under the black plastic cover on the left side please? Can a GPS be plugged into it with a suitable plug or is it the CAN-BUS connection?

 

That is the interface for the BMW shop computer or GS-911 to talk to the bike.

 

Thank you.

 

Can anyone recommend a handlebar mounted switch for my LED spotlights please? Need to handle about 4 amps.

 

Something like this?
