2004 ford focus door lock/unlock wires

Hi to all,

I'm not 100% sure if I have found the correct door Lock & Unlock wires for my 2004 Ford Focus. I've got the Car's wiring Schematics for the central locking. I found that the DOOR LOCK wire is BLACK/ ORANGE at Grey connector in GEM & DOOR UNLOCK wire is BLACK/ GREEN at green connector at GEM.

Whilst testing as per Negative Trigger, I connected Negative probe of multimeter to +12V, and probed each wire with the positive probe. This is what I found:

DOOR LOCK wire: rests at around -8V and when pressing lock, goes to about -10.4V & rests at this voltage.

DOOR UNLOCK wire: rests at -10.4V & when pressing unlock, goes to -8v & rests at this voltage.

Have I got the correct wires? To make sure I got the right wires, I cut them, then activated  lock/Unlock  on the car, the doors still locked & unlocked.

I'm little puzzled, as I would expect the doors not to lock/unlock with the wires cut.

There are other similar wires with the same colour codes at the GEM, but none of them test like above. I will appreciate any help in finding the correct wires.

Thanks

Howie II You're GREAT!!, always happy to share your expertise & Knowledge! Its guys like you that make this forum!

Now it makes sense why the doors still functioned with the trigger wires cut!  I can take comfort in knowing I got the correct wires, as per your plug locations i.e. Lock is on end plug nearest to Throttle pedal(Grey plug) & unlock's on the next one up(Green plug).

The alarm's got six door lock/unlock wires with onboard relays, with respect to all other connections, I have been able to trace & interface to them with your help.

I have diode isolated all door triggers & Trunk pin also.

Finally, can I connect the Tach/ RPM signal at the Ignition Coil? its a BLACK/ Green at the multiplug, going to the ECU/PCM. I rather not hook up at the injectors.

Thanks again
