02 Hyundai Elantra w/ factory power locks

Try this, go to passenger front door, push doorlock plunger up and down, if the all the doorlocks lock and unlock, then you can look for a BLACK/ tan or yellow in kick panel. Either wire can be used to lock and unlock doors. If Open circuit doors will lock, if (-) doors will unlock. Try this diagram: Single wireASE Certified

a little word from someone who has done this car. the drivers door has a five wire actuator trigger system in it. which means that when you close the latch it locks all doors and vise versa. heres the problem you will most likely run into with that car. i own a 2000 elantra and with mine was the same thing but the difference between the two are and listen up to add an actuator you generally need the car to be equiped with a rod that goes from the lock tab to the lock unlock assemble in the door. i have that in my car as well as most cars. but you dont in 2001 and up i have seen many elantras have a cable. now there is still hope. you have to gently attached to the actual trigger on the door meaning the thing you push in and pull out on the door panel. i have done this many times the way i did it though requires making a a custom strap. so what i am trying to say if you dont think that you can do it. take it to an audio alarm shop see if they will. because if you brake it you own it you have to buy another one. but if they agree to do it than they are responsible for it working.   But this may not pertain to you as your model may not be affected.Jon
