Hello . I ' m new to the forum and i undestand that you guys give very usefull information about wiring and many more things for cars. i ll get to the point and i will explain you my problem.
I have a Honda civic 98 1.4.
I bought the car used and the seller tell me tha it hasn't a cental automatic door lock unit.
It has a GxB alarm unit .
I wanted to put a central automatic door lock unit so i baught 2 door lock motors to put them on.
When i opened the door i noticed on Both doors where mounted motors and wiring although the hook that connects the motor to the door to unloc/lock was missing.
I watched both and noticed that both were in 'closed' possition . i tried to test them with my hand but both the 2 little arms of the motors dont move.
The motors have 5 wires
White
Black
Blue
Brown
Green

I folowed the wires and they're connected to a relay with 5 pins Excactly like this picture.
i descibe where the wires are connected too .

Now i want your help with this and i want to ask you the following questions.

Is there a possibility that the motors work but arrent'connected proprely ?
How can i check if they're dead ?
Can the motors work without wires from the keylock ?(because i don't see any wires connected to any control unit or my alarm)
and if yes ? from where they controlled ?
If no can i connect the door motors to my alarm ?
And if yes How ?
As i said i bought allready 2 new lock motors but they have only 2 wires a blue and a green. if i connect them on the white and brown wire i hear from the relay a click and they don't work. if i put them straight to my cars battery the work . also the new motors can move with the hand but the old one does't .
Thank you and sorry for the big post and my english i hope you undestand me .
I wish you could help me

Leave what you have in, that relay you imaged should be either blue or grey from the pin layout, it's Italian and it's a dedicated dual relay with a 3 sec coil shutdown. try grounding either the white or the brown lead coming from that relay after making after making sure it has live and ground. that should work your existing motors. That white and brown will; then go to your existing alarm's neg lock and unlock wires. You should also be able to work by locks by turning the key in either front door.

Thanks for your replies guys.
The first diagram shows 2 relays but it has only one.

I will ground the white blind wire to see what happens.
the relay has a gray cover and a black where the pins are.
i remind you that no wires goes from motor to the keylock how it's activated ?

i don't have the manual for my alarm so how can i see what colors are the larm's neg lock and unlock wires, there are at least 20 blind wires coming out of the alarm can you inform me how can i spot them ? there are whites(one with a 7,5 fuse on it ,oranges,greens,one blue with a 6 volt power, reds, and some i don't remember i will upload a photo of the whole mess as soon as i can to show you whats going on there ....

Your motors have microswitches in them, when you turn the key it pushes down the shaft part of the motor which activates the microswitch switching either brown or white to ground. This then activates the relay unit which activates the other solenoid (or actuator or motor all mean the same thing). Grounding either brown or white will do the same thing.
