    Cool, thanks!

    Just got my transmission adapter mailed from UK today...not bad! It took as long for PayPal to "clear" the paypal check to them as it did to ship it here....lol. "Clear" an electronic check, horses pattoot!

    Craig mailed it from UK on March 17th, it arrived in my home mail slot on March 28th. Ten days. Thanks, Craig!

    Now, a nice warm evening of work and to get it installed... photos, I promise...

    Great diagram, you removed all of that annoying thinking from the install. Thanks.

    Yeah, That's been my experience with the wrap too. That and instruments blanking out at higher RPMs (my timing light for example). I was wondering about tapping into the wire from the points near the coil, or off the dyna booster, now it's all coming together.

    Thanks, good replies here from you guys.

    I have the same problem, how to connect the Koso speedmeter (trhree wires) to a Acewell sensor (two wires).

    The Acewell sensor:

    Have anybody connect the Acewell sensor to a koso speedmeter??. Y have read the post, but yhave not seen the exact connection betweem the two devices.

    Thanks from Spain.

    Ooooh... nice looking instruments!

    Did you make the bracket? Very nice!





    Regarding the two wire/three wire, I would try emailing Craig at Acewell UK ( he has posted above in this thread) and ask, as well as the technical support for Koso.

    Thanks bpeckm & polloasado: :thumb
    I will send a email to acewell uk, but today is weekend and i want to install the sensor today or tomorrow.
    The panel is a 2 mm. steel laser cut with the pattern as i sent in AutoCad format to a company in Madrid
    I have seen that for example DimitriG has installed a koso intstruments (similar as mine) with the sensor Acewell ¿How do you connet between the 2 and 3 wires?
    More photos:

    The four indicators are Harley Daviddson accesory that i bought in Madrid, and are connecterd directly (without resistors) and the battery and another circuits run properly.

    Turns out the ACE-11 speedo sensor I ordered from the UK is not compatible w/ my Motogadgets Tiny.

    The Motogadgets Tiny requires a Reed sensor.

    I figured this out just after ordering. It's a nice quality unit, I'm bummed I can't use it.

    If anyone's interested in buying this unused sensor for $24 post paid in the US, send me an email.

    If it will work with my Trailtech I'll take it.

    Not sure if it will work. You should contact Trailtech and ask. Don't make the same mistake as me, ordering late night and looking at my manual a few days later.:dutch

    I just emailed Trail Tech. In my searching for more inf I found a place in Florida that offers the speedo sensor for 19.95.

    While installing the Acewell, I figured I would clean up the inside of my bucket... it had some "extra-long" wires with a bootload of crimp connectors, so I pulled it all out and re-routed, and it came out pretty nicely....

    [​IMG]


    ....but I DID manage to eff up my clutch bypass switch, so I will have to order a new one... those suckers are quite delicate in how the wires attach to the switch itself, and my old wires were stiff and in all the twisting and fidgeting managed to snap off one of the TINY spade lugs on the switch itself... aaargh...

    Will have to wait til another day to get a "glamour" shot of the whole Acewell installation.

    Turns out that the Trail tech units are all reed type sensors as well. So the Acewell BMW sensor only works with the Acewell units. Bummer!!

    A note about the Acewell 2853: Obviously now that they don't import the 2802/3, the 2853 is what I went with. I re-oriented the circuitry and do-dads in the pod itself so I could mount it off-center:

    [​IMG]

    And it is definitely not a "pry off" case. It is threaded - I will have to clean up the nicks now, but that's a small price to pay. I must say that it is nice and sealed in there as well. (I made sure to add some extra sealant when I put it together)

    Also for my bike ('78 R80) the wiring diagram is wrong on here. Pin 12 from the square rubber connector is definitely common ground and not a green/black switched power. The other wires seemed right though. Good thing I tested them.

    curious- I'm not sure what you mean by this- I'm considering getting the 2853 as well. what are the differences and why did you need to get inside?

    looks great!
