Datatool System 3 Alarm - Remove Or Disable?

definitely remove! - if it has a mercury based movement sensor then it's only a matter of time before this breaks down leaving you stranded. Removal is not that bad, with a lot of:- patience, a meter and snips/soldering iron&solder/connectors/crimping tool/shrinkwrap/insulation tape (delete as applicable). As you strip everything off to get access to the loom where wires have been intersected, you will hopefully be able to match all of the snipped loose ends by the wiring colour coding of your bike, this and a live supply and possibly several earths.

 

Most of these systems including the popular META alarm, tap into the starter solenoid/relay or ignition circuit and a live feed for the LED light. My experience with Datatool is not good, having had two fail on previous bikes so I switched to META on my wife's Monster, I am not sure about Datatool's installation protocols, but in the case of META, for obvious reasons, the tell tales on the all black wiring coming from the alarm unit are removed after installation, so if that applies in your case, you are going to have to root through the loom and remove any added insulation to find at what points the loom has been intersected, desolder any connections and make good the insulation of the OEM wiring.

I can't speak for Datatool but I replaced the META M357T alarm on my wife's Monster (as the old unit failed after 12 years) and it hasn't caused any issues yet, PROVIDING it is mounted in a position that is A) not obvious and B) not prone to any ingress of water/moisture. Not always easy on a naked bike but worth the effort. Still going strong after 10 years of use. Just be sure to protect it, if you wash your bike. On a side note, the META unit does draw some appreciable current, so a battery tender is a must if you don't want to flatten it when the bike is stored for long periods, such as over the winter months. I made an aluminium enclosure for my wife's unit, which protects it from the heat and yes is NOT under the seat, which is where most of them end up (especially on early Monsters) and the first place a toe rag will look. I'm obviously not going to divulge where it is on a public forum but safe to say, it would be a complete and utter nightmare to get to it if you were planning on ripping it out. I appreciate it won't prevent physical removal of the bike from it's secured place if accessed, BUT it is one of several measures in force to detract an amoeba from trying to make off with it, whilst it is screaming it's head off. I've several other layers of security that would alert me to the presence of a low-life LONG before they actually got to the bike itself, as any alarm is just part of the solution, not the answer.

 

I removed mine on my 998 and it's a fairly easy job. I wouldn't disable it.
