The TAG Direct Fit Wiring Harness hooks your towbar lights into Toyota LandCruiser Prado 120 Series from 06/1999 to 12/2009 and Hilux Surf from 08/1993 to 12/2010. The loom runs from the rear light cluster to the towbar over about 1–2 m of cable, so you can tow standard trailers with working brake, tail and indicator circuits every time you head off down the highway or into the scrub.

The kit uses automotive-grade insulated cabling, an in-line blade fuse and a relay module sized for standard trailer lighting loads around 10–15 A. The direct plug connection into Toyota style sockets means no cutting of factory wiring, which keeps the vehicle harness intact for long-term touring. With install time around 0.5 hr in a workshop, this is a smart buy for Prado and Hilux owners who want tidy wiring before they get out there again.

Q: Does this harness replace the need for a universal trailer wiring kit?

Yes, this gear is a vehicle-specific direct fit harness. It connects to Toyota plugs on Prado 120 Series and Hilux Surf models rather than splicing into wires. That keeps the factory loom intact and simpler to fault-find later. It is intended as the primary towbar wiring setup for these vehicles.

Q: Can I install this harness at home with basic tools?

Yes, many owners with basic hand tools can fit it. The approximate fitting time is 0.5 hr in a workshop, so allow longer at home. You will need access to the rear light area and towbar mounting zone. Always follow the supplied instructions and check all trailer lights before driving.

Q: Will this wiring harness affect factory reverse sensors or fog lights?

No, this harness does not include reverse sensor cut-off or fog light cut-off functions. The data lists both as not applicable. That means the kit only handles trailer lighting circuits. Your existing reverse sensors and fog lights will continue to operate as usual on supported vehicles.

Q: Do I need any software coding or scan tool after fitting this harness?

No, diagnostic coding is not required for this harness. Once the loom, relay and fuse are installed correctly, the trailer lights run off the existing circuits. You can confirm operation with a trailer board or test light. If any light fails, re-check earth points and plug seating before seeking workshop help.

This direct fit wiring harness suits Toyota LandCruiser Prado 120 Series models built from June 1999 to December 2009. It also suits Toyota Hilux Surf models built from August 1993 to December 2010. Approximate installation time is 0.5 hr according to supplier data. Diagnostic coding is not required after installation. The harness does not interface with reverse sensors or fog light cut-off systems.
