FAQ – Frequently Asked Questions

Which wiring kit (7- or 13-pin) should I choose?
For basic lighting functions like tail, brake and indicators, a 7-pin kit is usually sufficient. For reverse lights or permanent power use, a 13-pin kit is recommended.

Is coding or activation required?
Yes – depending on the trim and equipment. Discovery IV models with comfort and assistance packages may require enabling additional signal functions so everything is recognized correctly.

Can I install the wiring kit myself?
With proper tools and some knowledge of car electrics, yes. If you are unsure or warning messages appear, it's advisable to have it installed by a professional.

Is the wiring kit weatherproof and durable?
Yes – our wiring kits are constructed with weather-sealed plugs, corrosion-resistant materials and solid insulation to handle moisture, temperature changes, and challenging conditions.

What should I do if warning messages or electrical faults appear?
These often occur due to loose connections, incorrect wiring, or incompatible components. Proper installation—and, if necessary, using a relay or module—usually resolves these issues and ensures stable operation.
