I've powered my Garmin gps from the tailight. It is on the same circuit as the horn and turn signals and has a 7.5 amp fuse. If you have your camera on and honk the horn, you may blow the fuse. You might be able to fix this by installing a 10 amp fuse, but I wouldn't go any higher than that.
Why would you?
Honda has made the courtesy to pre-wire two accessory connectors on a 7.5A separately fused switched 12 circuit on the bike.
One is under the front cowl, the other is under the seat. Why would you butcher a lights circuit if these are available?
Use one of the accessory plugs. If you are uncertain about obtaining the sumitomo connectors to do the job properly, then you can buy a Honda accessory socket for under the rear seat that just plugs in and gives you a “cigar lighter” type socket.
Butchered wiring is something I really cannot stand. Particularly unnecessarily butchered wiring.
I would love to see a tutorial on how to tap into the front accessory socket (near the front headlamp) with simple cut and crimp connectors and bypassing the need to purchase sumimoto adapters.
I mean with crimp caps like they use with car stereo installation.
If you’re serious, then just cut the Sumitomo one off, and crimp on whatever you like.
But, a pack of four Sumitomo pins and seals, including postage, cost me under £1, and the plug shell to put them into is already on the socket, so why would you want to do it with non-standard ones? If you mean those cheap blue or red ones you buy in accessory stores, then it’s worth pointing out that they’re not weatherproof, and never last long.
Even if you have a specific type of connector that you want to use, maybe because you swap an accessory from one bike to another regularly, it’s easy to make a short “whip” harness with a Sumitomo one end, and the connector of your choice the other.
I’m all for saving a few quid, and I’m as creative as the next man when it comes to recycling stuff to keep my hobbies afloat for minimal expense, but these bikes aren’t yet dirt cheap secondhand bangers. At the moment they’re still pretty expensive things, and personally I don’t see any sense saving pennies on the job if doing so is going to be devaluing the bike by many multiples of that.
Whatever, it’s your bike and your wallet. I’m sure you can find a tutorial on fitting whatever kind of crimp it is you favour.
The Sumitomo pins might only be £1 but the crimp tool must cost a bit more. You only get to connect one device. I ran one lead from the battery to a relay and a connection from the Rear light to activate it. I also installed an auxiliary fuse box so I can connect loads more I only have heated grips and a USB socket at the moment but I have lights on the way.
Anyway I have the 2015 model and I don't think that the front socket is in the same place.
