new alarm locking problem

Hello, im installing a new alarm in my 300E 86' and the only problem i cant fix is unlocking the doors. They lock fine with the remote. What i have done is taken the green wire from the passenger kick pannel and inturupted the signal that runs on it to control the locking. Here is the diagram i used to make it work. But i have a problem on my alarm sheet it has 2 wires for lock/unlock. Here is how it shows up in my guide. ---Green (-) lock (+) unlock ---Blue (+) unlock (-) lock Can anyone help me fix this. Im totally stumped, the only thing i can think of is that its not giving a ground signal to unlock, so i hooked up the blue wire to a relay to make it output a ground signal and it still doesnt unlock.

can anyone just tell me what signal (+ or ground) comes out of what wire on lock and unlock??

Which alarm are you using? The blue and green wires you mention are they coming out from the alarm or are they the doorlock wires in the vehicle?ASE Certified
