You're most welcome. Adding power locks and windows (especially with remote capability) gets complicated because Nissan doesn't use generic harnesses with the unused connectors taped back. That means upgrading to the factory setup will most likely mean changing both Door Harnesses, the Main Harness, and possibly the BCM. The door connections will generally be identical for all trim levels, but the lock and window wire positions will be un-stuffed. Your best bet would be to gut a pair of JY doors for a complete set of switches, door harnesses, lock actuators, and regulators with motors, then add the needed wires externally to the Main Harness under the dash. Then see if it works, if not then your BCM will need an upgrade too. You're talking about a big, complicated exercise no matter how you cut it.
The other option for door locks is to get a universal kit that comes with a separate remote. The kits are actually very inexpensive, but of course the mechanical hookup and linkages will need a lot of measuring, fabricating and fiddling:

For windows, your best option is still to raid the JY for a set of power window regulators, but add your own switches and relays instead of trying to duplicate the factory setup.
