Frequently Asked Questions (FAQ)

1. Should I go for a 7-pin or 13-pin wiring kit?

A 7-pin kit is generally sufficient for simpler uses like bike racks. If you need additional lighting, cabin power in the trailer or more comfort features, a 13-pin kit is the better choice.

2. Will parking sensors automatically disable when towing?

Yes, many of our wiring kits include this feature to prevent false alerts when a trailer is connected.

3. Is coding or activation required after installation?

It depends on your vehicle’s features. Models with advanced electronics, LED lighting or comfort systems may require coding or activation for full operation (monitoring, warning displays etc.).
