it will need to be reprogramed if you dont have a matching key.(call around to you local lcksmith if you go this rout much much cheaper than dealer) ..if it comes with the matching key all u have to do is swap over the chip to your existing key and wall..A....(otherwise it will not disable the immobilizer and start if the key and ecu are not paired)......

I' in the process of wiring the fi/c. The ecu pinouts that Jeff posted are positive (+) right? So all of the positive wires from the fi/c would connect to those but where do you connect the negative wires from the fi/c? (crk-, cam-, inj-, ect...) Please help.
