nissan single wire lock to dual gnd out

The car has the two wire system. The actuator has one wire.

Your original post states your car is a 1990 240sx which generally uses the Type F system with a 94 Maxima actuator which is usually 2-wire. Is that correct?

1992+ 240SX uses the Type F system. Before 1992 the 240SX uses the Type B system. Mine is 1990 Type B. It needs a momentary Ground to trigger lock or unlock. If I give it a constant ground it continuously powers the actuator and makes it stuck in one place. The actuator I have gives a constant signal of either Ground or Open. I took it from a 1994 Maxima rear passenger door. Going the other way round would be much easier but I can't get my head around making it work nicely with the parts I have.

Something here I don't understand. All actuators except deadlocking types have two (motor) wires. If your vehicle right now is a type "B", just go to the control unit or find the existing motor wires parallel them onto the new one.

Yes, I already did this. Also I already have the alarm system hooked up and locking and unlocking the doors.

But I want the factory function of the driver's door lock controlling the passenger door lock like how it did when there was just a switch in the driver's door instead of an actuator. So I want to convert the lock and unlock signal of the Type F lock to the lock and unlock signal of the Type B system.

I bowed out to this one, but Howie, he's not talking about the motor wires. He's talking about the micro-switch built into the actuator. Kinda like on a 5-wire aftermarket actuator that has the black, white, and brown wires for the internal micro-switches. His actuator only has one wire coming off his internal micro-switch. That wire reads ground in one position and N.O. in the other. He wants to integrate that into a standard Neg. pulse existing locking system in his car. This way when he moves the door switch on the drivers door, the passenger door lock will follow(central locking system)

Bloody well easier to buy an SPAL or MES 5 wire aftermarket and incorporate that into a type B system! Or change the internal micro switch (good luck). Or change the driver's door switch (but where in heaven's name will you find one that close to ground one way and open circuits the other?). I bowed out on your 04 Maxima, pulled the wires from the mirror switch? If he installs the existing actuator in the passenger door and retains his driver side, as long as he doesn't use the single "trigger" wire it will work. To control it from a passenger door switch, just use a normal SPCO momentary back to the lock control unit.

Thanks Flobee4, your explanation is exactly what I meant.

I had a SPAL type actuator, it worked, but the movement didn't suit the car and placement was exteremly hard. It locked me out a few times because internally the way I had to place it, it would move enough to trigger the lock signal with enough vibration from closing the door.

There's a possible way to change the internal microswitch but it would be very delicate and not suitable for inside a car door.I already have a switch in the driver's door as part of the 94 Maxima actuator that is close to ground one way and open circuit the other.For someone Flobee4's 04 Maxima right?I've thought of a way to do it, which is to attach the original switch back to back with the actuator i've put in there. That makes the lock quite heavy though. I can see a way to do this electonically but it involves holding relays continuously most fo the time which I'm not sure is a good idea or not.

That last idea is a real no-no. Unless you use latching relays, with ordinary batteries you'll have a flat battery every time.

Understanding how the F type locks work, my question is what voltage and polarity is used so the actuator knows when to lock or unlock. You apply a ground to unlock and break the connection to lock on the same wire. The actuator wire has to be tied to something for it to know these changes are happening? 12v constant? Lower voltage? I know usually it would go to a control unit first. That's what is making it hard to answer or figure out a solution.
