Caution: To avoid the risk of pyrotechnic devices being triggered (seat belt pretensioners or airbags) the use of multimeters or other electrical measuring instruments on these elements is prohibited.
Do not leave unused +12V terminals exposed to the atmosphere without proper protection.
Make sure there is no contact between the wiring and the fuel or brake lines.
Avoid laying electrical wiring in areas where the temperature is above 100°C.
Before performing any work on the 12V power supply wiring, the negative battery terminal must be disconnected.
Attention:
- To avoid noise, increased wear, short circuits, etc. after reconnection, it is necessary to mark the wiring and the method of connecting the connectors.
- To avoid any damage during removal, make sure that the wiring is warm from the fasteners (fixing clamps, plastic holders, electrical tape, connectors, etc.).
To prevent damage to electrical wiring, it is necessary to ensure that the surrounding areas do not pose a mechanical hazard (for example, sharp corners, opening or moving elements, etc.)
Electrical wiring must be installed at a distance of at least 30 mm from moving components (belts, pulleys, steering column, etc.)
Depending on the environment, ensure that unused connectors are properly insulated.
All connections (connectors) used in the engine compartment must be insulated; do not remove insulation around connectors.
Do not connect the ground wire to studs with insulation protection (for example, painted).
Do not use more than two ground terminals on one stud.
Do not use power grounds on the same ground points as electronics grounds.
To prevent water from getting into the connectors, it is necessary to lay the wiring in such a way that when approaching the connector, the wiring goes from the bottom to the top.
When connecting between fixed and movable components, fix the wiring to the fixed part.
Crossing of battery power wires (positive and negative) may lead to confusion; it is necessary to lay the wires separately from each other.
For fastening electrical wiring:
- use plastic holders, making sure that the color markings match,
- do not use steel clamps that do not have rubber protection,
- use the clamps built into the wire harnesses during replacement procedures,
- do not leave steering column wiring unprotected.
Make sure that:
- the jumpers are properly secured,
- the connectors are properly connected and secured.

Lay the wires in such a way that where they are visible, everything looks aesthetically pleasing. Try to lay the wires according to the marks made during removal.
It is prohibited to lay wires through grooves and protrusions (risk of wire fraying due to friction).
It is prohibited to route multiple wires through one clamp.
Do not fix connectors or wires in places where drilling is possible (for example, at the location of the license plate).
