I got the wiring diagram for my car. I understand everything but two things.

1. In the insturuction for the alarm,It tells me to connect the green and blue for the lock & unlock function. What I do not understand is from the wiring diagram it has (car diagram) (power lock/power unlock) & (lock motor/unlock motor) I do not know which is the correct one to splice into.

2. The instruction says for the remote starter connection the white wire to the starter input. Its also says that some vehicles may be equipped with a second start wire. Does the Maxima have a second start wire? From the wiring diagram I have, it says there is a second starter. It say to install a relay if it does... which I understand but is this normal?

Thanks
