The application is an older motorhome with two doors.  The current goes to the drivers door with one power lock switch from a 1965 chevy.  It the button is held up then the two door locks go up in each door. If down then they go down. There are two wires only that go to each actuator the pushes or pulls the actuator. The switch then just changes direction of the current. 

The alarm has three methods, positive , negative trigger, or external actuator. 

The alarm has the built in  relays but for this system I will need to add an additional relay??  Otherwise once the alarm applies current to either wire, it will short out and go to ground.

A diagram or explanation on how to wire would be appreciated.  Below is the little motorhome.

Sounds like a good ol' 5-wire setup, this site has a great diagram of what you're trying to do.
