Special Features of Altea XL

❓ Frequently Asked Questions (FAQ)

➤ Are all Altea XL models identical, or are there differences that matter for wiring kits?
There are differences – especially in year, rear bumper design, sensor or spoiler inclusion. These details impact cable routing and connector length.

➤ Do I need a 13-pin wiring harness, or is 7-pin enough?
A basic trailer with lighting can often use a 7-pin harness. For additional functions like fog lamp, reverse lamp, or trailer power supply, a 13-pin version is more suitable. Plus, some legal or inspection requirements stipulate certain pin counts.

➤ Will the wiring kit interfere with my existing sensors or parking-assist features?
If installed correctly – no. Our kits are designed so that sensors, cameras, or parking assist systems are not disrupted. We also offer variants with relays or disable features when necessary to avoid dashboard warnings.
