The Erich Jaeger Direct Fit Wiring Harness hooks your SsangYong Rexton G400 from 09/2017 to 02/2021 into standard trailer electrics so you can tow with factory-style plugs at the back. The multi-core loom reaches from the rear light cluster to the towbar area on a vehicle body length of about five metres, so you can tow box trailers or campers without splicing random wires. The kit runs copper conductors with insulated sheathing rated for 12 V automotive circuits, so the trailer lamps draw the same power as the Rexton tail lights. The control module sits in a compact housing under about 15 cm long, so it tucks behind trim without rattles. The trailer socket housing bolts to common towbar plates around 5 mm thick, so the plug stays solid on corrugated tracks and city streets alike. This is smart buy wiring gear for long-term use.

Q: Does this harness suit all SsangYong Rexton models?

No, it suits the Rexton G400 built from 09/2017 to 02/2021 only. The connectors and cable lengths are matched to that specific body and wiring layout. Other Rexton variants can use different plugs and light configurations. Always match the build date and model code before ordering so the loom fits correctly.

Q: Is this harness intended for trailer lighting circuits only?

Yes, this kit is for standard trailer and caravan lighting circuits. The loom links brake, tail, indicator and related signals from the vehicle to the trailer socket. High-current charging or electric brake power usually needs separate cabling. Use this harness as the lighting interface and add any extra circuits with suitable rated wiring.

Q: Can the control module be mounted outside the vehicle?

No, the control module is meant for installation inside the vehicle trim area. The housing is sized for protected interior locations near the rear panel. Mounting inside reduces exposure to water and stone strike. Keeping it inside the trim also shortens wire runs and helps the plugs stay clean.

Q: Do I need extra brackets for the trailer socket?

In most cases the supplied socket housing bolts straight to a standard towbar socket plate. Many towbars already include a flat plate with existing holes. If your bar has a different arrangement you can use a suitable plate or adapter. A solid mounting keeps the plug stable when towing on rough roads.

Suitable for SsangYong Rexton G400 built from 09/2017 to 02/2021. Harness connects to factory wiring using model-specific plugs. Kit fits vehicles prepared for towing electrics at the rear loom. Professional installation is recommended for correct integration with vehicle systems.
