Pay attention to the length of the cables: for most sedans and hatchbacks, 6 meters is enough with a margin, but owners of minibuses or pickups may need to buy extension cords. ACC — You will need to purchase it separately if you plan to connect to the ignition.

Required tools and materials for installation

For proper editing 70mai Midrive UP02 The Hardware Kit will require not only the kit itself, but additional tools, and without them, the process can be delayed or end in damage to the wiring of the car.

If you plan to connect to a regular rear camera, you will additionally need a connector for a camera connector (for example, for Toyota or Hyundai, they differ). CAN-tyre might be needed CAN-analyzer to determine the correct signals for activating parking.

Don’t skimp on tools: a cheap multimeter with a large margin of error can show the wrong voltage, which will lead to the failure of the Hardware Kit. We also recommend buying plastic corrugated cables to protect cables from rubbing – this is especially true for wires passing through doors or under the seats.

⚠️ Note: If your car is equipped with a Start-Stop system, connect to a lighter or a lighter. ACC This can cause a malfunction of the recorder, in which case you need to use a voltage stabilizer or connect directly to the battery via the relay.

Connection schemes of the Hardware Kit to the on-board network of the car

There are three main ways to connect. 70mai Midrive UP02 Hardware Kit to power your car. The choice depends on how you plan to use the system:

2. Connection to ACC (ignition: the system activates when you turn the key. ACC fuse-box or behind the ignition lock.
3. Direct battery connection – provides parking operation, but requires the installation of an additional relay to protect the battery from discharge.

For most users, the second option is optimal – connecting to the ACC. To find the right wire, use the multimeter:

1. Transfer the multimeter to constant voltage measurement mode (20V DC).
2. Connect the black probe to the mass (any metal part of the body).
3. Check the wires in the fuse box or behind the ignition lock, and the wires you want to see will show you. 0V when the ignition is switched off and 12V — switched on.

Critically, never connect a Hardware Kit to a wire that is constantly supplying voltage (such as a light bulb wire) and this will result in battery discharge in a few hours.
