I have a 1998 Hyundai Elantra and had the rotors replaced, you will have to have a shop to do it because they have to be pressed off and then back on again with a specialized machine or tool. Of course unless you have that tool you can do it yourself. Good luck.
there's no such thing as a Hyundai ''lantra'', its elantra If it's the same as Elantra try modifiedlife.com. They got free wiring diagrams for many makes and models. Sorry. There is a Lantra. It was released in Australia by Hyundai during the late 90s. There is a sedan and a sports wagon.
