1991 toyota helux, alarm/remote start

I'm currently installing an alarm and remote starter in my friends 91 helux (auto), but having a few problems.

I got a wiring diagram from this site, and all of the wires made sense. It took me a while to find a few of them, like the nuetral kill switch, but the only one i havent found yet is the parking lights wire.  This is my first alarm install, so i was expecting a few hiccups, but i know how to work a voltmeter and have installed many decks and subs and amps.

The alarm is a carvox, no model number, but it is a 2 way pager system.

Now, the problem i'm having is that the everything on the alram is working, including door locks, but the truck wont start! i havent put in the starter kill yet, but the car will not even turn over! I'm thinking it has to do with either the wiring for the remote starter or the nuetral kill switch, but havent pinpointed the problem yet! so i was wondering if anyone has had the same or a similar problem, and what they have done to solve it! I'm going to start unhooking things and playing around, starting with the remote start.

Thanks in advance for any responses!

well the nuetral safety switch is supposed to be grounded during park and nuetral, and hot in any other gear. And yes, i checked to see if it was working, and it seemed to be.

Also, the battery is not dead, the headlights are still giving a full power beam and the power windows are still moving fine.
