here's the wiring diagram i use when i do remote starts. they say the lock and unlock harness is somewhere in the drivers kick but i can never find them there on lx's so check above the brake pedal there's gonna be a gray harness chilling up there with three wires to it and you have to tug on it a bit to get enouch slack to tap into it. but all in all the car is relatively easy to do. good luck
