2001–2003 Chassis Codes: XD (3rd Generation, Pre-Facelift) | Model Years: 2001, 2002, and 2003
This page provides the complete 2001–2003 Hyundai Elantra radio wiring diagram for the pre-facelift XD chassis. Use this guide when installing an aftermarket head unit or troubleshooting your factory stereo in a 2001, 2002, or 2003 Hyundai Elantra.
The XD-generation Elantra was an all-new design for 2001, the first Elantra assembled across multiple Hyundai plants worldwide, and it replaced the wagon body style with a five-door hatchback offered alongside the sedan. The sporty GT hatchback trim added a stiffer suspension, alloy wheels, and a blue-lit instrument cluster, but used the same head unit and speaker wiring as other trims. Hyundai gave the XD Elantra a more significant facelift for the 2004 model year (sometimes referred to as XD2), which is covered on a separate page since the head unit connector changed at that point. This page covers only the pre-facelift 2001–2003 sedans and hatchbacks.

Frequently Asked Questions
What harness adapter fits a 2001–2003 Hyundai Elantra radio installation?
The pre-facelift XD Elantra uses the factory connector shared across most early-2000s Hyundai and Kia models, and installers commonly pair this generation with the Metra 70-7304 Wire Harness Adapter. Always confirm wire colors at the factory plug before cutting, since Hyundai used this connector family across several model lines and minor pin differences can exist between individual vehicles.
Is the wiring different between the Elantra sedan and GT hatchback in this generation?
The GT hatchback introduced with the XD generation added a firmer suspension, alloy wheels, fog lights, and a blue-lit gauge cluster, but it shares the same Head Unit connector and front speaker wiring as the sedan. Rear speaker placement differs slightly because the hatchback’s rear cargo area and parcel shelf are shaped differently than the sedan’s trunk and rear deck, so confirm your body style before assuming rear speaker locations carry over exactly.
Is there a factory amplifier in a 2001–2003 Hyundai Elantra?
No pre-facelift XD Elantra sold in the U.S. market came with a factory Amplifier or branded premium audio system. All trims, including cassette and CD-equipped GLS and GT models, drive the speakers directly from the head unit. This means no Amplifier bypass harness is needed when installing an aftermarket head unit on any 2001–2003 model.
Does the 2001–2003 Hyundai Elantra have steering wheel audio controls?
Steering wheel-mounted audio controls were not offered on the pre-facelift XD Elantra. Higher trims such as the GT added cruise control switches to the steering wheel, but no factory trim included radio or audio function buttons on the wheel itself. No SWC retention interface is required when replacing the Head Unit on any 2001–2003 model.
What dash kit is needed to install an aftermarket stereo in a 2001–2003 Hyundai Elantra?
The pre-facelift XD Elantra uses a single-DIN factory Head Unit opening on most trims. A dash kit designed specifically for the 2001–2003 Elantra is recommended over a universal kit, since the surrounding climate control and vent trim pieces are shaped uniquely to this body style and differ from the redesigned dash introduced with the 2004 facelift.
