keyless entry for VIOS / YARIS 2003

[stud858]

Hoping someone may have some tips for me to get wiring right for keyless entry installed into Toyota VIOS 2003.

I've browsed the net for help on wiring but my findings in the car are not matching with what I'd expect to see.

It should have been a simple matter to find "open" , "lock" and "detection" wires in passenger side

This is what I've figured out so far.

Passenger side behind kick panel.- I have found a wire that shows 0V and jumps to 12V when the lock button is pressed on drivers door.

and also another wire showing same readings for the unlock button. This would suggest positive triggering, right? But everywhere on net says toyota is negative triggered for door locks. These same wires are also on drivers side.. I could not find any other voltage signal changes on the other wires on passenger side when doors locked/unlocked. It is common for the "detection wire" to be on the passenger side, but I couldn't decipher it.

Drivers side - besides the lock and unlock wires mentioned above, I found three other thinner wires on the top smaller harness showing 9.7V and going to 0V when either the lock or unlock is pressed. Again I could not decipher a "detection" wire and wonder what these wires are for.

I tried ignoring the "detection" side of things and simply wiring up the lock and unlock wires to the keyless entry module..

I press the remote to unlock the door and I hear the faintest of effort from the door motor, The doors don't unlock. So either I need to investigate more about this so called "detection" wire or the module is not supplying enough power to the motors to open the lock.

Any help appreciated, Have a rippa night.

Ok. I got this sorted. 

Traced. Wires from door lock switch on drivers door.  Wires go to ground when button pressed for lock and unlock. Don't forget to disconnect Battery when testing for continuity otherwise you'll blow a fuse.
