· When wiring, first arrange the outer wiring harnesses, then arrange the wiring
harnesses in the cab;
· When wiring, pay attention to avoid high temperature, oily, sharp and abrasive
areas, fans, exhaust pipes and other nearby areas;
· When wiring, keep a certain length to avoid over-tightening and loosening; the
wiring harnesses layout should be smooth and cannot be twisted;
· When wiring, leave enough length in case of wheel turning to right/left all the way
because the wheel angle sensor will rotate together with steer wheel;
· After wiring, cut off the extra length of cable ties. After complete the installation,
please store the original vehicle accessories properly and clean up the garbage.
b) Electrical connection method and precautions
· Before connect to receiver, display, and steering wheel connectors, please connect
to battery first to avoid damage caused by direct power-on or multiple power-offs;
· In the process of connecting the power cord to the battery, first connect to the
positive electrode then to the negative electrode;
· Pay attention to the use of the wrench when connecting the positive electrode, and
it is strictly forbidden to bonding (when the wrench contacts the positive electrode of
the battery, the other end of the wrench is strictly prohibited from touching any
conductive items, especially the metal parts of the original vehicle);
· 12V / 24V battery, when using the original battery power supply, please connect
the positive wire to the positive electrode and the negative wire to the negative
electrode;
· 12V / 24V battery, when additional battery is connected in series, connect the
positive wire to the positive electrode and the negative wire to the negative
electrode of the other battery, as shown in the diagram below.
