Wiring indication

Power connection
The standard power supply ranges from 11V to 36VDC.
During installation, the negative side should connect to the ground. Do not connect with other ground wires simultaneously.
Ignition wire
ACC line (orange) connects to the vehicle’s ACC. detecting ignition. Be sure to check if it’s a real ignition wire i.e.power does not disappear after starting the engine.
Relay wiring
Relay’s white line(85) connects to the positive side of the fuel pump while the yellow line(86) connects to the device’s relay control (yellow line on power cord).
Find the fuel pump of the vehicle and cut off its positive power line. The positive side of the fuel pump connects to the green line (87a) while the side closing to the starter motor connects to the green line(30), as the below chart. The switch of the two green lines has the same effect
12V relay standard. The device is suitable for vehicles with 12V supply. If the vehicle power supply is 24V, use 24V relay.
SMS configuration
Tracked by mobile phone
Send the command URL# by SMS to the device’s SIM card number. The device will reply with a map link. Click the link to have the location displayed on Google Maps on your mobile phone.
If device in somewhere not positioned, the device will reply “Positioning, please wait for a moment or “Positioning fail”.

Troubleshooting
| Type | Use |
| Unable to connect to tracking platform | Check the APN and IP settings. Check whether the data service of SIM card is enabled. Check the balance of SIM card. |
| Tracker shows offline | Check whether external power is still connected. Check if the vehicle entered network blind area. Check the balance of SIM card. |
| Unable to locate | Make sure the top side facing upward without metallic things shielded. Make sure it’s not in area with no satellite coverage. |
| Location drift | In area with poor GNSS signal(tall building around or basement),drifting may happen. Check whether vibration happens around to trigger the accelerator. |
| No command reply | Make sure command fonnat is correct. Vehicle may be in network blind area. Make sure SIM card is well inserted and have SMS service. |
