1999 Mercury Sable Door Locks

Ok I have a small problem an I hope somone can help!!!

Car: Mercury Sable 1999

Problem: Door Locks

power lock: (-) negative

power unlock: (+) positive

The problem is that the alarm (Valet, Model 563T "Manul can be found here: http://www.directed.com/guides/manuals/ig/valet/N563T_6-03.pdf ) has two wires in th "door lock harness, 3-pin connector" (located on pg. 15 in the manual) 1-green an 1-blue.

the   Green is    (-) lock  (+) unlock output    and     Blue is  (+) lock   (-) unlock  output

but as I stated above the 2-wires need to see (-) in order to do thier seperate jobs.

example: to lock the power lock wire needs to see (-)    to unlock it needs to see (-)

so does the alarm just send a negative on both wires or does it send a (-) to 1 an a (+) to the other

if so how do i correct it to be negative only!

thanks in advance!!!!!!!!!!!!!!,
