The Sealey TB55 conversion lead is an essential tool for vehicle owners and caravanners who need to bridge the gap between modern 13-pin Euro vehicle sockets and older 7-pin trailer setups. It is designed for those requiring simultaneous N-type (lighting) and S-type (auxiliary) connectivity for 12V systems, offering a reliable, plug-and-play solution. While it solves major compatibility issues, users should ensure their vehicle's wiring harness supports the extra load of both S and N functions before installation.

No, this conversion lead is strictly designed for 12V towing equipment applications.
Yes, the S-type socket on this lead provides the necessary connection for auxiliary power functions like fridge cooling, provided the vehicle is wired for it.
The sockets are typically marked or color-coded according to industry standards, where N-type is for lighting and S-type is for supplementary power.
The materials are chosen for external use, but the electrical pins should be protected from extreme moisture and road salt when not connected.
No, this product is specifically for converting a 13-pin Euro vehicle socket to 7-pin trailer plugs.
Ensure the 13-pin plug is fully seated and locked. Clean the connector pins with electrical contact cleaner to remove any surface oxidation.
Verify that your vehicle's 13-pin socket is actually wired to provide auxiliary power, as some vehicle installs only connect the lighting circuits.
To set up the TB55, first ensure your vehicle's 13-pin socket is clean and free of debris. Align the keyway on the lead's 13-pin plug with the socket, push in, and twist clockwise to lock. Connect your trailer's 7-pin N and S plugs into the corresponding sockets on the lead.
Compatibility is limited to 12V systems; do not attempt to use this with 24V commercial vehicle setups. For maintenance, keep the connector pins clean using a specialized electrical contact cleaner spray. Avoid pulling the cable by the lead itself when disconnecting; always grip the hard plastic housing to preserve the internal wiring connections. Store the lead in a dry environment when not in use to prevent oxidation of the metal contacts.
