9 MOUNTING RECOMMENDATIONS

9.1

Connecting Wires

• Wires should be connected while module is not plugged in.
• Wires should be fastened to the other wires or non-moving parts. Try to avoid heat
emitting and moving objects near the wires.
• The connections should not be seen very clearly. If factory isolation was removed
while connecting wires, it should be applied again.
• If the wires are placed in the exterior or in places where they can be damaged or
exposed to heat, humidity, dirt, etc., additional isolation should be applied.
• Wires cannot be connected to the board computers or control units.

9.2 Connecting Power Source

• Be sure that after the car computer falls asleep, power is still available on chosen
wire. Depending on car, this may happen in 5 to 30 minutes period.
• When module is connected, be sure to measure voltage again if it did not
decrease.
• It is recommended to connect to the main power cable in the fuse box.

9.3 Connecting Ignition Wire

• Be sure to check if it is a real ignition wire – power does not disappear while
starting the engine.
• Check if this is not an ACC wire (when key is in the first position, most electronics
of the vehicle are available).
• Check if power is still available when you turn off any of vehicles devices.
• Ignition is connected to the ignition relay output. As alternative, any other relay,
which has power output, when ignition is on, may be chosen.

9.4 Connecting Ground Wire

• Ground wire is connected to the vehicle frame or metal parts that are fixed to the
frame.
• If the wire is fixed with the bolt, the loop must be connected to the end of the wire.
• For better contact scrub paint from the place where loop is connected.
out in a very low impedance point on-board vehicle network. These
points in the car are the battery terminals. Therefore, we recommend
connecting the power of FM1200 (wire GND and POWER) directly to the
battery terminals. Another valid option is to connect the wires to the main
POWER cable inside the fuse box (if there is none, then to the power
supply where the fuses of vehicle's computer are), wire GND must be
connected in a special point, designed to connect GND vehicle
computer. Connecting the GND at an arbitrary point to the mass of the
car is unacceptable, as static and dynamic potentials on the line GND will
be unpredictable, which can lead to unstable FM1200 and even its
failure.
PAY ATTENTION! Connecting the power supply must be carried
