This TAG Direct Fit Wiring Harness hooks your Peugeot 508 straight to a towbar socket so the trailer lights match what your tail lights are doing every time you brake or indicate. The kit is built for Peugeot 508 SW wagons from 06/2011 to 12/2018 and Peugeot 508 sedans from 06/2011 onwards so you know the loom length and plugs line up with factory points. Bolt it in once and get out there with the van or box trailer.

The harness uses automotive grade cable and a dedicated control module to handle standard 12 V trailer lighting loads without cooking the car wiring when temps hit 40 °C on a long highway pull. The kit includes the socket housing, mounting plate, fixings and clear printed instructions so you can tackle the install with a tidy finish. For regular towing this is a smart buy that keeps your setup tidy and compliant.

Q: Does this wiring harness include the trailer socket and mounting hardware?

Yes, the kit includes the trailer socket, housing and mounting hardware. You get a socket insert and cover that match standard 12 V trailer plugs. A mounting plate is supplied so the socket can be fixed near the towbar. Screws and other small fittings are included to secure the hardware during installation.

Q: Is this harness compatible with both Peugeot 508 sedan and 508 SW wagon models?

Yes, the harness suits both Peugeot 508 sedans and 508 SW wagons within the listed build years. The vehicle specific design means the loom length and connectors line up with factory wiring points. This helps keep the install neat without cutting the main vehicle harness. Always double check your build date against the 06/2011 start point before ordering.

Q: What trailer circuits can this wiring harness support?

The harness is intended for standard 12 V trailer lighting circuits such as indicators, brake lights and tail lights. The control module and socket are laid out for common trailer wiring patterns. This means basic trailers and campers with standard light loads are covered. Higher draw accessories like fridge circuits or electric brakes usually need separate wiring.

Q: Are installation instructions supplied with the kit?

Yes, printed installation instructions are included in the box. The guide shows the connection points on the vehicle and the layout for the trailer socket. Following the steps helps keep the wiring tidy and reduces the chance of electrical faults. If you are not comfortable with auto electrics it is worth having a qualified installer fit the kit.
