Installing door lock actuators

I hqave a 97 Ford Ranger that I am installing door lock actuators on.

I have a Hammer FM 2009 lcd pager/alarm, and I am installing aftermarket door lock actuators.   There are no factory locks.  This alarm module has the power door lock/trunk relays built into the module, but the wiring diagram says to hook up the aftermarket actuators uses external relays.  There is (-) unlock adn (-) lock coming out of the module.  I thought that the aftermarket lock actuators would be hoooked up with a (-) trigger.  I didn't think I needed relays unless I was hooking they up to a (+) trigger.  I could send the wiring diagram if necessary.  Hope somebody out there is smarter than me.  I really didn't want to let the smoke out of the module if you know what I mean.
