7- or 13-pin connector options: Whether you need only basic lighting or additional features like reverse lights, permanent live power or accessory connections.
Weather-resistant, high-quality materials: Sealed connectors and insulation designed to resist moisture, corrosion and harsh temperature changes.
Compatibility with sensors & control units: Cable routing and connectors take into account the vehicle’s lighting, sensor and electronics setup to minimize warning lights.
Secure installation & proper fuse protection: Correct fuse sizing, clean cable routing and solid connectors are key for reliable, long-term operation.

Towing & Load Specifications

According to public sources, the broked (braked) towing capacity of the Lexus IS 250 is approximately **1,500 kg**. :contentReference[oaicite:2]{index=2}

The unbraked towing capacity is significantly lower – in many cases around **750 kg** depending on trim and legal registration. These are guideline values; always check your vehicle registration or owner manual for your specific model. :contentReference[oaicite:3]{index=3}

Installation & Technical Notes

Check whether your car is equipped with reversing camera, parking sensors or driver-assist systems, as these might need activation or coding when adding trailer lighting.
Ensure connectors are fitted securely; run wiring so it is protected from heat, moisture, or abrasion.
Select suitably rated fuses and make sure the vehicle’s electrical system can handle the load from trailer lights and any accessories.
Choose a wiring kit that is mechanically and electrically appropriate for the towing weight you plan to use, particularly if you tow often or with heavier trailers.

FAQ – Frequently Asked Questions

Which wiring kit (7- or 13-pin) should I use?
A 7-pin wiring kit is usually sufficient for basic lighting (tail, brake, indicator lights). If you want reverse lights, constant live power or accessories, a 13-pin option is better.

Is coding or activation required?
It depends on year and equipment. Vehicles with many assist/comfort features might have control units that require recognition of newly added signals; activation or coding may be necessary.

Can I install the wiring kit myself?
Yes — with proper tools and basic knowledge of vehicle electrical systems installation is feasible. If warning lights appear or if equipment is complex, professional installation is safer.

Is the wiring kit weatherproof and durable?
Yes — our wiring kits use weather-sealed connectors, quality insulation and materials that withstand moisture, corrosion and environmental stress.

What should I do if warning messages or electrical faults appear?
Usually they come from loose connectors, improper wiring, unmatched components or under-dimensioned fuses. A clean installation and possibly use of relays or auxiliary modules often solve these issues and restore reliable operation.
