1998 Maxda Protege Alarm

Ok, couple of things...

First up, door locks...Directechs says that lock needs a negative trigger through a 4.7K Ohm resistor, and Unlock needs a negative trigger to the same wire.  I understand that part, but it also says that I must use relays.  Why must I use relays??  Why can't I just hook up the unlock wire from the alarm (Viper 771) to the wire in the car, and also hook up the lock wire the same way (except with a resistor on it).  I don't understand why relays are needed.

Next, I'm doing remote start, but the car has standard transmission.  So, I must bypass the clutch.  I know how to do it, but I do have a question that is related.  Once I bypass the clutch, the car can be started without pressing it in, so I guess theoretically, if the car isn't left in neutral, it will lurch forward (It's my girlfriend's car, and she NEVER ever leaves it in anything but neutral).  I know that some cars have a neutral safety wire, but as I understand it, this is only on automatics so that they can't be started in "drive".  Am I right about this??  Or does this car (stick shift) have a neutral safety wire too??  If it does, I would rather use it...it's just much safer obviously.  If not, is there any other way to keep the car from starting in anything but neutral??

Thanks in advance.

Use a door popper actuator, it will reset all the time and do the job you are looking for.  2 wire actuators should only be used for lock / unlock...
