04 toyota highlander locks

hello everybody,  i'm working on a 04 toyota highlander and i am having problems making the door locks work.  i have a wiring diagram,  but i have a few questions. first the wiring for all the locks is done in the passanger door right?  and how does the lock detection wire read and does th elock and unlock wires reasd like normal.  i know that some of the questions are a little basic but this is the first time for me to do the lexus locks so a little guidance would help a great amount.Nicolas White

your wires are also found in the passenger kick...diff. colors though  Lock is white, unlock is brown and purple (2 wires diode isolated, pulsed at the same time)  The detection wire reads NEG(-) when unlocked, and nothing when locked.
