sentra 90' door locks (not standard)

Hi there . I have the 90' sentra . i checked the door lock section Nissan's Single Wire '91-'95 using 1relay and 1 diode and the Nissan's Single Wire '91-'95 using 2 relays . i know that i have the one wire type door locks. when grounded it opens and when cut it locks. the problem is that the diagrams shown for the one wire only will work if the one wire works with a pulse . in my car the one wire must always be connected for the locks to remain open . in the diagram , it will open when it gets the unlock pulse but will lock when the pllse is gone .these single wire diagrams shown will only work with door lock that needs a pulse . in my car i need current to ground for the lock to remain open at all times. What can i do ? i have neg triggered output pulse from my alarm hornet 725t."I'm So Loud It Hertz"

im not sure about cars over there. my notes have it as a neg system. see if these wire are in the car Power Lock ORANGE / BLUE Power Unlock GRAY/RED AT SWITCH OR DOOR HARNESS IN DRIVER KICK PANEL #201- See Negative Pulse Door Lock Diagram.

it is negative .My car had central locking . that is where you close the driver door and the other 3 doors lock . i have replaced the switch on the driver door that does the switching and put in an actuator and wired parallel to the other doors. the control panel on the driver door locks and unlock them well. the relays are built in the control panel and has lots of semiconductor that i do not wnat to interfere with. the switch which i removed just connects to ground when the doors are open and disconnects when closed. this switch has a green with with a black stripe on it. this can be used to control the unlocking and unlocking but i need a circuit with relays for it to work.

central as in when you locked the drivers door all the other did the same?? same for unlocking the drivers door? in the case you can/could have added an actuator to the drivers door and wired just that motor up. that way you wouldnt have to change anything out. if its not too late, you might want to start from scratch. let me know and i will walk you through it david

My car had central locking . the driver door had a switch inside the door that activated the other 3 doors whenever you pull or push the driver lock. that switch no longer exist because i removed it and put in an actuator and now all 4 doors have power locks. The wires that goes to the (removed) switch is what i want to use to control the doors locking and unlocking. when you ground the wire that came from the switch the doors will lock , when removed it will open . it is now simply finding a way to use a circuit to control this wire. if i use the neg output when armed (orange wire from alarm) via a relay then it would work but i would not have ignition controlled locks. do you follow so far ? my e-mail address:   iboodhoo@petrotrin.com"I'm So Loud It Hertz"

yes i do. where you not able to add the motor with the switch in place? then you could have wired up that one motor with a couple of relays and had all the features that you wanted. if you can i would put the switch back and go the other route. let me know what you think. i can help you with the idea above, but you have me beat on the other way. Good Luck

The motor has the same brackets as the switch. so you can only put one in at a time in the door.The motor replaces the switch. right now the switch at the control panel is working to lock and unlock the doors. i want to keep that feature . i can't tap in that switch because of teh amount of surface mount electronics built in the control panel . I'll have to make use of the wire from the removed switch."I'm So Loud It Hertz"
