viper 3000 in a volvo 240 me

I have a 1983 Volvo 245 Wagon that I am adding a Viper 3000 alarm system 
to. However, I am a bit stumped by the Vipers' door lock harness wire
connections to the Volvo's factory central locking system.
I would prefer to retain the current functionality. That is, the car
can be unlocked by key (in the driver's door lock), or by lock plunger
(inside the car). But, I am willing to forgo this functionality if it
becomes a problem.
Below are pictures of the PDF files from the Viper's manual and the Volvo
factory manual. The Viper's page shows the connection for the door lock
harness. The other pictures show central locking system for the 240 series.

The picture below shows an unmodified picture of the central locking 
system in the 240 series. 
The dark lines indicate an always-on 12 volt signal, while the "white"
lines show inactive lines (unless a switch is activated)

  " IDEA 1
 
Please notice I had to add an actuator to the driver's door (line J
from the legend) in order to have the driver's door open with the remote
entry key fob.
This photo shows the input lines both the unlock (D) and lock (E) relays
have been cut. The following connections have been made from the Viper's
door lock harness:

H2/B is connected to the output of key switch and the door switch
H2/C is connected to the input of the unlock relay
H2/D is connected to an "always on" terminal on the fuse panel
H2/E is connected to the output of key switch and the door switch
H2/F is connected to the input of the lock relay
H2/G is connected to an "always on" terminal on the fuse panel

An actuator (or motor) is connected in parallel with the rest of the 
actuators (for the driver's door).

My only fear for this setup is that the existing system will not function
via the key switch or the door switch (since it is effectively disconnected
from the system unless the key fob is pressed)

" IDEA 2  

Please notice I had to add an actuator to the driver's door (line J 
from the legend) in order to have the driver's door open with the remote 
entry key fob.

This photo shows the input lines both the unlock (blue wire) and lock
(yellow wire) connections have been cut. The following connections have
been made from the Viper's door lock harness:

H2/B is connected to the blue wire that leads to the output of unlock
relay
H2/C is connected to the blue wire that leads to the added actuator
H2/D is connected to an "always on" terminal on the fuse panel
H2/E is connected to the yellow wire that leads to the output of the lock
relay 
H2/F is connected to the yellow wire that leads to the added actuator
H2/G is connected to an "always on" terminal on the fuse panel.

My fear for this type of connection is that the relays onboard the Viper
will not funcion unless either the key switch or the door switch is activated
(completing the circuit and providing a trigger for the Viper's onboard
relays

Idea 3

Please notice I had to add an actuator to the driver's door (line J 
from the legend) in order to have the driver's door open with the remote
entry key fob

This photo shows the input lines to the added motor connected directly 
 to the Viper's door lock harness. The following connections have been
made from the Viper's door lock harness

H2/B is connected to the green wire that connects the door/key switch
to the unlock relay
H2/C is connected to the blue wire of the added actuator
H2/D is connected to an "always on" terminal on the fuse panel
H2/E is connected to the red wire that is connects the door/key switch
to the lock relay
H2/F is connected to the yellow wire of the added actuator
H2/G is connected to an "always on" terminal on the fuse panel

An actuator (or motor) is independant of the rest of the actuators.

I think this one works the best because I have connected H2/B and H2/E
to wires that are always "hot". The actuator should fire when
the key fob is pressed popping actuator J (which should cause the rest
of the central locking system to unlock the rest of the doors). Popping 
actuator J is like using the key or door switches (in theory).

 
Please let me know if any ideas will work, or provide some other ways 
to connect the Viper's door lock harness to my Volvo's central locking
system.

Thank you very much for your time!

As you have already stated, your Volvo has central locking, meaning when you lock or unlock the driver's door the remaining doors do the same. You do not hook up any of the Viper's wires to the Volvo's door locks, just to your aftermarket actuator. Adding an actuator to the driver's door will not stop the key from manually opening the lock so long as it is installed properly. To wire your actuator you would follow the diagram listed on pagethis page. Each pin of your door lock harness matches a pin in the diagram listed.

This is so simple, read my post again it's the easiest way, it was suggested to us by an alarm manufacturer back in the '80s, you only need neg outputs from the alarm to accomplish it. This assumes you've changed the  original switch in the driver's door for a 5 wire actuator or tandemned the actuator with the original switch. Come to think of it I use the same process in early 90s UK Maimas and Saabs.
