If the vehicle has towbar wiring preparation, installation can usually be done in about 60-90 minutes. Depending on the trim and electronics, activation or coding may be required afterwards so that all functions are properly recognised and no warning lights remain. Professional installation is recommended.

Frequently Asked Questions (FAQ)

1. Is a 7-pin wiring kit enough, or should I choose 13-pin?

If you only need basic functions like tail lights, brake lights and indicators, a 7-pin set is often adequate. For reverse lights, rear fog light, signal monitoring or comfort features, the 13-pin variant is recommended.

2. Do parking/reversing sensors deactivate automatically when towing?

Yes – many vehicle-specific kits include this functionality to avoid false alarms or warning indicators when a trailer is connected.

3. Is activation or coding required after fitting?

Depends on the model year and your equipment. Vehicles with comfort or assistance features often need coding or activation so all signal and lighting functions are properly recognised without warning messages.
