Connecting power source
1. 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.
2. When the module is connected, measure the voltage again to make sure it did not decrease.
3. It is recommended to connect to the main power cable in the fuse box.
4. 3 A, 125 V external fuse

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

Connecting ground wire
1. Ground wire is connected to the vehicle frame or metal parts that are fixed to the frame.
2. If the wire is fixed with the bolt, the loop must be connected to the end of the wire.
3. For better contact scrub paint from the spot where loop is going to be connected.
PAY ATTENTION! Connecting the power supply must be carried out in a very low impedance point of on-board vehicle network.
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 AGT400-M operation and even its failure.
