daihatsu door locks

I need some help with daihatsu door locks.  There is 4 wires in the harness one wire changes from 0v to +5v (cant remember if it was lock or unlock) the 2 middle wires show voltage spikes the quickly drop back down to 0v straight way.  and the last cable shows no voltage at all.

I think this is a 1 wire door lock system. am i correct?

btw  If i cut the wire that shows +5v when lock, the other doors dont respond.  and if i ground one side of the cut cable it will unlock.  But when i tried to pulse the cable with +12 i killed a fuse.

Does the drivers door have a lock/unlock switch... ?

If NOT you need to add an actuator, to move the lock mechanism in the door.

Hi KarTuneMan

The doors dont have a actual lock and unlock switch (like in the center console of camrys). 

But when u insert the key into the drivers door, all 4 doors will lock and unlock together.

When putting key into the passenger door lock, only the passenger door responds. 

just like hyundai,95 rodeo,kia you need an actuator in the driver door to work with the alarm if not the factory driver motor will freeze up and you won't be able to open your door. 

thanks guys. 

i thought i was able to connect to the factory locking system.  I'll head out and but a actuator kit.

bmwboi.....remember...you only need 1 actuator, drivers door only...K

good luck dude

Thanks KartuneMan and Nava94 

The security system is 98% done, Door locks worked like a charm.   But I have a problem with the door triggers.   I found the door triggers that will only show neg when open.  

My CHEAP alarm from ebay willshows me a 5+ on the door trigger wire.  Is there a error in my manual that shows me the wrong wire?

Here is a link to the alarm from ebay.  http:///.com.au/dll?ViewItem&category=31250&item=4546164469&rd=1

Thanks again for your help guys.
