Toyota Fortuner wiring harness replacement — AN160, 2015–2025

Harness assemblies we build for the Toyota Fortuner

Each assembly is a separate part number with its own drawing and test fixture, so you can order the complete set or replace one failed loom. All five share the same splice points as the factory harness.

Assembly	Build specification
Engine & ECU harness	Firewall-to-engine routing with injector, coil, O2, cam and crank branches, sealed ECU header and the OEM connector series retained so the loom plugs in without re-pinning.
Body / cabin harness	Main body loom carrying the fuse and relay block, BCM connectors, interior lighting, audio, immobilizer and convenience circuits on the original circuit count.
Chassis, ABS & suspension harness	Wheel-speed, ABS/ESP sensor, ride-height and fuel-tank branches in abrasion-resistant conduit with sealed sensor connectors.
Tailgate & rear camera harness	Hinge-loop section on high-flex cable, bend-tested to 300,000 cycles before release.
Lighting & front-end harness	Headlamp, fog, horn, washer and front-sensor branches with sealed, keyed connectors.

Known failure points on high-mileage Fortuners

These are the faults that bring Fortuner owners to us. If your symptom matches one of them, the loom — not the component — is usually the cause, and a section replacement is often enough.

• Rear-body loom water ingress through the tailgate grommet
• Third-row seat and power-liftgate loom pinching
• Chassis loom chafe near the fuel-tank bracket
• Corroded ABS sensor connectors after flood exposure

How we build it

• Drawing first. We map your sample or OEM drawing into a circuit list, connector list and 2D layout, and send it for approval before production.
• Connector parity. The original connector series is retained for the AN160 / AN150 so the loom plugs into the existing ECUs, BCM and sensors without adapters or re-pinning.
• Wire spec matched to the branch. 0.35–0.5 mm² for signal, 1.0–2.5 mm² for lighting and motors, 4–6 mm² for feeds, with heat-rated insulation on engine-bay runs.
• 100% test. Continuity, short and pin-out test against the drawing; hipot where HV is involved; bend test on hinge loops. Test record ships with the carton.

Toyota Fortuner harness questions

What does a full wiring harness for a Toyota Fortuner cost?

A complete set for a Toyota Fortuner (AN160 / AN150, 2015–2025) typically runs USD 320–1,450 depending on circuit count, connector count and whether HV sections are included. A single engine or body assembly is USD 120–520. Send the OEM part number and a photo of the label for an exact figure — quotes are issued within 24 hours.

Can you supply a Toyota Fortuner harness when the factory part is discontinued?

Yes. For discontinued Toyota Fortuner looms we rebuild from your original harness: we map every circuit, identify the connector families and produce a new drawing. This is the standard route for the AN160 / AN150 generation now that dealer stock has dried up in most markets.

What is the lead time and MOQ for a Toyota Fortuner harness?

Sample in 7–10 days after drawing approval, production in 25–30 days. MOQ is 50 sets per part number, with one unit accepted for a paid sample. Repeat orders on an approved drawing are faster because the test fixture is already built.
