Read this before you order
Engine harnesses are built to the exact engine, transmission and emissions package the car left the factory with. Two Santa Fes of the same year can take different harnesses. Buy this on the part number, not the year. Find the number on your old harness or have a dealer look it up against your VIN, and make sure it comes back 91405-0W040.
Fits
- 2010, 2011 and 2012 Hyundai Santa Fe (CM chassis)
- Applications that call for Hyundai 91405-0W040
Does not fit
- 2007-2009 Santa Fe — those use different harness numbers
- 2013 and newer Santa Fe / Santa Fe Sport — a different generation entirely
- Any Santa Fe whose harness number is not 91405-0W040
Check this before you order
- Match the number: it must be 91405-0W040.
- Confirm your engine and transmission combination against the harness you are replacing.
- Compare the connectors in the photos to the ones on your car. Ask if you want a close up of a specific plug.
Condition
Used OEM part pulled from a vehicle. It came out complete rather than being cut out. Look through every photo before you buy so you know exactly what you are getting.
What is included
The harness as pictured. Modules, relays, fuse boxes, sensors and grommets are not included unless you can see them in the photos.
Why used OEM
Hyundai engine harnesses are expensive new when they are available at all, and the aftermarket does not make them. A used factory harness gives you original connectors, correct wire colours and the right lengths, which is what you need when the old one has been chewed, melted or spliced.
Shipping
Ships from Illinois. Shipping is included in the price. The harness is coiled and boxed so connectors are not crushed in transit.
