Any unused wiring should be removed or taped up and securely
fastened to the bike.
9. WIRING CONNECTIONS
The Datatool Evo Plus motorbike alarm system is designed to work on
12 volt negative earth electrical systems only. Do not install this
product to a positive earth machine.
The main positive and negative connections are the most important
wires of any alarm system as they supply the power to make most of
the other functions work.
Main Positive Supply (red tagged wire)
The red tagged wire is the main power supply to the alarm and
requires a permanently live 12v positive feed.
Many machines are now equipped with a dedicated permanent 12 volt
positive feed designed to power an alarm system. Alternatives can be
the clock or fan fuse. The rating of this fuse should be be no more than
10amps. If the rating is below this the fuse may blow when indicators
ash via the alarm system.
The alarm is equipped with internal protection to deal with shorts on
the indicators but it is always advisable to t a protection fuse as this
protects the wiring from the fuse to the alarm unit itself. Where
possible the fuse should be tted as close as possible to the source of
power. The supply should never be taken directly from the battery.
Main Negative Supply (black tagged wire)
This wire can be on the frame or within the wiring harness but should
never be taken directly to the battery. Any harness based earth should
be tested to ensure it is a true earth and does not change when the
ignition is turned on and switches are operated. If unsure refer to the
machine’s wiring diagram.
We advise the use of harness based earths in most cases. Frame
earths, especially on anodised frames, can be very poor.
