    Hello All,
    I am a new member to this forum but have read many posts relating to the dreaded datatool alarm system.

    I have an 04 Triumph Speed Four which has always, since purchase, had some minor issues with the alarm.(I think it's a Datatool S4). Recently however after the battery again discharged the alarm system has finally locked me out completely.

    In the morning after battery charging, bike started fine, that afternoon the alarm will not deactivate.The key fob led illuminates however Indicators don't flash and turning ignition on activates siren and key fob(s) will not silence or reset alarm. I noticed that the wire to the rear LED was corroded and broken but speaking to Datatool they assure me that this will not effect the alarm operation.

    As stated, I've read many posts relating to this, all seem to have the opinion of ripping the alarm out, a simple job requiring the linking of pins 1+2 and 3+5 on the multi-block connector... simple if you have a multi-block connector, which I don't appear to have. My datatool seems to be spliced into to main wiring loom with any colour coding tags removed. To complicate matters further I do not have a code for the alarm so resetting using that option is also not possible.

    I've attached a couple of pics, for what they're worth, showing the connection of the alarm (with the heatshrink removed). Any USEFUL help/advise or wiring schematic for the speed four would be appreciated.

    Many thanks.

    My son and I had a similar problem with a 600 Yamaha Fazer many years ago.
    A rather drastic solution but we found the simplest way to resolve the alarm problem once and for all was to replace the whole wiring loom with a secondhand one.

    Probably not what you wanted to hear but its a complete solution as when the data tool was originally fitted the wiring would have been extensively modified to make it difficult, if not practically impossible to remove.

    Thanks for reply..
    Having looked on Ebay etc none seem to be available at present and previously sold items have gone for £100+... Time I have, money I don't :(
    Did you consider splicing in another Datatool alarm? Was that an option or more trouble than its worth.

    Wherever the alarm fits into the main wiring loom, it should just unplug, and then you replace it with one of these, which you should be able to get from your Triumph dealer. I did this with my thunderbird, with no problem at all. They call it a blanking plug.

    The blanking plug would be the simple solution if the bike had originally been fitted with a Triumph Datatool alarm. However in the OP's case it appears from the photos that the alarm fitted was wired into the loom rather than using the OBD port, (if the Speed 4 even had that port fitted)
    That means rather more drastic measures are required to remove the alarm in this instance.

    Do you know if the Triumph TT600 is exactly the same as the Speed Four? Seems that wiring looms are available for the TT600 for about £50.. however am I correct in also assuming that there are variations of these bikes i.e. one with carb and plugs and one with EFI? ( sorry don't know the limit of your knowledge of this but assume you know more than me)!

    ASSUME - makes an ASS out of U & ME

    @Blanketstacker You should be able to unwrap the wiring and remove the alarm that way. you may need a soldering iron to melt the solder on the wires. Then just tape up and do a reset.

    I thought of that but surely the wires left on the loom must go somewhere? Or are they just dedicated wires for the alarm system? Are the bike loom wires the ones that would go into the multi-terminal block that everyone else's alarm simply plugs into? ... I know nuffink

    I'm sorry I don't know for certain if the looms are the same but I doubt it.
    The looms will be different for a carbed bike and one with EFI.
    It might be possible to remove the alarm as Joe McDonald has suggested but you will need to be very careful in reconnecting the original wiring.
    The Datatool alarm splices into the wiring loom specifically so it is difficult to remove. You will probably need some spare wire and be good at soldering, plus the wiring diagram and make sure that you connect the same coloured wires together.

    Best of luck!!
