Honda CRF 250 Rallly aux power plug

Honda 250 Rally Aux power source

I MAY have found the aux power plug under the left side upper front fairing. There is a thick cable running to the lights and it has an unused end with cap on it.

With a right Honda connector plug, one should be able to easily plug in to 12V aux power. I tested the plug and it is dead when power is turned off, but gives out 12 volts once the ignition is turned on. Next job is to confirm that this plug can actually safely be used and find out where I can score the proper female plug that fits.

DO NOT MAKE ANY INSTALLATIONS, MODS ETC. BASED ON THE INFORMATION ABOVE.

The plug removed

 

UPDATE

I have succesfully used the above plug as a switched power source to charge my phone & GPS.

There is also another source for switched power under the seat. Read more -> https://honda250rally.com/2017/05/10/aux-power-source-ii/

***THE SOCKET UNDER THE SEAT CAN NOT BE USED FOR POWER**
It is a diagnostics plug.

  1. The Honda aux plugs on the 500x have the mating connection already there. You just need to pop out the blank seals and put in .090 pins. Perhaps the Rally is the same.

    1. Hi Gar, have you got a link to the pins? The Rally plug sounds exactly the same as the 500x, it just needs pins inserting.

    2. Hi Gar,

      I’m in Bangkok and would like to know where you got the crimped pigtails from. I have a CRF 250, but the Honda dealers aren’t exactly too savvy around here.

      Was it just a local bike mechanic?

      Thanks,

      John

      1. I emailed cycleterminals (see post above) and asked them if they knew of someone who would make pigtails for me and overseas mail them. I explained about not wanting to purchase my own crimp tool, and ship it to Thailand, just to get six terminated pigtails made. 🙂 555 They were happy to help out. The pigtails came complete with the rubber donuts to seal up the Honda factory connector. I’d be really surprised to find even a huge Bangkok Big Wing that had the pins and grommets.

      2. Oh Ok, I got it now Gar, thanks. I misread your post.

        I may be going that same route. You are right, even the Bigwing guys are confused about what to do; they just want to take the shortcut and wire directly to the battery.

        Thanks for the reply, cheers.

  3. Hi guys.
    I live in Bali Indonesia and basically have the same issue. The Honda teams here also are lost.
    I have to assume that plug is fused? Did any of you add an additional 3 or 5 amp blade fuse to the connection?
    Have you guys had any issue with it since installing?

    Thanks
    Ken
