❓ Frequently Asked Questions (FAQ)

➤ Do I need a specific wiring kit due to the battery size / EV features of the Smart #3?
It depends on whether the harness needs to support additional functions like trailer power supplies, reverse lights, or extra lighting. Our kits are designed to be compatible with both the 49 kWh and 66 kWh variants and handle different performance levels safely.

➤ Is a 13-pin harness necessary, or is a 7-pin kit sufficient?
For just standard lighting, brake lights, and indicators, a 7-pin kit will often suffice. If you plan more advanced features like trailer power, reverse lamps, or additional lights, we recommend a 13-pin version. Check your trailer's equipment and how you intend to use it.

➤ Will sensors or electronic assistance systems be affected by the wiring kit?
Only if the harness is poorly installed. Our vehicle-specific kits use the correct connectors, protected wiring, and suitable relays or modules so that sensors, cameras, and assistance systems remain fully functional and free of warning signals.
