791 into 2003 350z

I am installing a 791 into 2003 350z track (6 speed manual).  I have installed quite a few alarms but I was wanting to clear up some questions I had before installing this alarm in a few days.  Before I get jumped on by some people about not searching first...trust me I have.  I have looked at g35 coupes, sedns, altimas, maximas, etc.  I usually find the year and not color im looking for or verse versa. Anyways the questions...

1.)  Okay, I know there is a neutral safety wire comming out of the ECU...can anyone clear up what color it is and possibley what pin number and/or harness?

2.)  Clutch bypass, I read several people saying use a relay and some that says other stuff...Can some please clearify the proper way to do a clutch bypass with a relay?(relay pin number with wire description would be great)

3.)  Next, thing is that I have directech print out of my car and it says to go into the door for the unlock/lock...but I have read on here and few other sites that you don't have to do that.  Can someone explain these wire locations and colors.  Also, I want to be able roll up my windows with Lock/Arm and be able roll them down with Aux channel.  How would I do this?

4.)  When I install everything in few days I am installing a Alpine IVA-D310 with the navigation unit...What is the wire color for the vss wire?  I know it is behind AC unit... 

(please give me wire colors for 2003 Nissan 350z track  manual)

***Thanks a lot for reading and helping***

My email is littlemac504@aol.com for those who to send this in private message or whatever.

(please give me 2003 350z colors, so it may save me some time)

THANKS!!!

...sorry i left one out....

5.) I read that you can use the "wait to start wire" and wire it into relay and hook it up to the parking brake wire and the car won't crank unless the parking brake is pulled up.  Can anyone please tell me this setup...relay pin configuration and wire colors for them?

Thanks again!

I know my questions arnt in detail that is because I havn't taken my car apart and it has been several months since I have worked on G35/350z.  And since I am installing this on my own car, I never have time or energy to do it when I get off work.  Because I am senior at Mercer University with chemistry major.   And then working 30 to 40 hours week installing wears me out after I have been in classes half the day...

So, the main reason I even posted anything was to save me some time when I do get around to installing it all.  And the shop I work at doesn't allow you to work on your car the day you work or if the bays are full.  The bays are always full so I basically have to install stuff on my car outside my apartment late at night on campus(campus cops are always thinking I am robbing someone else car).

And where I work at we only deal with DEI products.  And I can get the 791 for around $150.  Which is a heck of a deal for what all it is capable of.  I havnt really heard much about 689M, so the hence of wy it didn't cross my mind. 

***Thanks for the info on the neutral safety wire and VSS wire.  Thats exact info I was looking for.  That will save hour or two of testing there.

Okay about the clutch I am still alittle hestiant...I tested the wires tonight and the fluke was saying that the wire is neither neg or pos triggered.  It was reading like 288 ohms. 

30- input from clutch switch (forgot color since i didnt write down when I was testing)

87-output from clutch switch

85-ground (i know it can be 85 or 86) but I do 85 out of habbit bc whenever a relay has spike suppression diode it has to be liek this or it wont work correctly.

86-starter wire?  I would put this on key side correct?
