2004 Corolla Keyless Entry

Unlock - Blue (-)Lock - Blue/White (-)Child Safety - White (-)All three are in the same harness in the driver kick panel. Just follow the wires coming in from the door to the plug that they go to. Use your factory alarm disarm wire to hit the white child safety if your unit has one. If not, use two diodes on your units unlock wire and set the unit for double pulse unlock. For testing the wires you will get a low resistance/continuity for the lock/unlock wires when you hit the driver door switch in its respective position. The child safety wire will show a low resistance/continuity when you put the key in the door and turn it to the unlock position.

green = lock blue / YELLOW = unlock both in same plug at drivers kick, always test with the key in the door locking it and unlocking it, and probing the wires to make sure they are the right ones for unlock.
