The TAG Direct Fit Wiring Harness for the Citroen C4 Grand Picasso 06/2013–12/2018 lets you hook trailer lights straight into the factory loom with the right plugs in the right spots. The wiring length matches the Grand Picasso tail so the socket ends up right near the towball and not hanging 200–300 mm short or long. That means you can tow the camper or box trailer without chasing dodgy light faults every trip.

TAG builds this harness with automotive-grade copper wire and protective sheathing sized for standard 12 V trailer lighting loads. The connectors line up with factory points across the rear so you follow existing mounting paths and keep the loom off hot exhaust sections by a safe 50 mm or more. It is smart buy gear for anyone looking to tow within the Grand Picasso’s standard rating without hacking into original wiring.

Q: Does this harness suit all Citroen C4 Grand Picasso models?

This harness suits Citroen C4 Grand Picasso vehicles built between 06/2013 and 12/2018. Outside those build dates the plugs and wiring layout can change which means this kit may not match the factory loom. Always confirm the compliance plate build month and year on your vehicle. Matching the range helps avoid fit issues and electrical faults.

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

Yes, this harness is intended for standard towbar lighting circuits on compatible trailers. That means brake, indicator, tail and related light functions that match the factory setup. Additional high-draw accessories may need separate wiring. Keeping loads within normal lighting levels helps protect the vehicle electrical system.

Q: Can this harness be removed if the towbar is taken off later?

Yes, a direct fit harness can be removed if the towbar is taken off. The connectors unplug from the factory loom without cutting the original wiring. This helps return the vehicle closer to stock condition. It also allows the harness to be replaced if it becomes damaged.

Q: Does the kit include a trailer socket bracket?

The product information only confirms a vehicle specific wiring harness for the Grand Picasso. Any socket bracket or towbar mounting hardware may be part of the separate towbar kit. Check your existing towbar for a socket mount plate before planning the wiring run. Using an existing plate helps keep the socket in a protected position near the towball.
