hey mates!
i have 4 door sierra without central locking
what do i need to convert it to central locking with keyless entry?

 

Electric Central Locking mechanisms off a higher spec sierra.

And an alarm (like a clifford, toad, etc...) with remote locking output.

 

where is the mechanism sorry if i am asking 2 much lol and what alarm would you recommend

 

If you want just central locking then look on ebay, remote central locking kits around Ł30, don't bother with the ford stuff, it's not as good ime, would be easier fit but can be unreliable, I use after market every time for cl kits.
If wanting to use with a alarm, then you don't need the remote function of the CL kit, so instead go to maplins, about Ł20 for a 4 door kit, I fitted one of these about 5 years ago on the astra for the gf and it's still perfect 5 years on.
To this I added a boot/hatch motor from the scrappies and simply joined into one side.
It's an absolute doddle to wire up, and to link in to the alarm.
For the alarm if wanted I would go toad, if you want a approved one a ai606, would need fitting and certing by someone, but if not fussed a toad sterling is the same quality, just research a bit to see what features you want in the different ones.

what i want to know is if there is an electronic "brain" or only four electromagnetic locks...
are the locks be controlled from the driver's lock or there is "brain"which controls all the others?
i am talking about the official central locking of 4 door sierra saphire

 

The standard C/L uses two way servos on each door and one for the hatch/boot, the central locking can be controlled via the driver or passenger locks, when you turn the key in the lock it switches one master (I.E driver or passenger depending which lock your operating) thus locking or unlocking the car respectivly as there all connected.

On MK1'S the C/L can only be operated from the drivers door but thats outside the discussion of this thread, these also used solenoid's.

Contary to the above I have never had a problem with the standard system on both our's.

What model do you have as even the basic model MK2's had C/L, I guess yours is an early Saph, I.E circa 1988?

mine is 91' without any extras...it doesnt have even a rev counter...it is tha 1600 cvh and i want to install centrall locking so i want to know what should i bye exhept from the four locks......
i wander if there is a brain too...that i should buy

 

Oh right, I bet your speedo shows 130MPH as well? No as I say it's just the five motors, the fronts of which are "Masters", the MK1 had a "Module" but the MK2 does not.

Martin

 

thank you very much....so the only thing i have to do is find only the four locks....because same people said me than i need and a "brain"(i dont know the exact word) but they weren't sure

 

Five motors if you want the boot to be part of C/L as well which it is in the OE setup, you then of course need to wire them in etc.

Martin

 

i found the three locks....i want one more...
but some people....tecnisians who i asked....said me that i neeid and the control unit....is there a control unit too?....to work the locks?does this unit control the locks?or wiring them up them alone is enough?
is there any diagram to help me do the job

 

No NOT on MK2, MK1 there WAS, the masters do as the name suggests and operate the rest of the locks, for this reason the doors will not lock if either of the front doors aren't shut.

If you want the diagram PM me your E-mail and I will send you a copy of the diagram over when I have a moment, it's a negatively triggered system via the key, the motors themselves have a permanent supply.

Martin

 

thanks you very much my friend! haw happy a am..!

 

two more questions!
do i need something calles central locking motor tailgate in order to work the central locking?
and do i need something more from the genuine central locking in order to install an alarm which will control and the central locking?or the four locks are what i ony need?

 

if it's a 91 spec then you won't need one for the boot

the facelifted ones after 90 spec have different motors to the pre 90 spec cars and are cable operated rather than rod

also the fronts have 4 wires and the rears have 3 which is easy enough to figure out which ones are slaves and which are masters

 

As I say there are five motors, one for each door and one for the boot as well, as yours is a early Saph you will need them all if wanting the OE setup, the facelift models had a mechanical remote boot release and fuel filler cap from inside the car.

Yes if wanting remote CL via an aftermarket alarm etc then it depends on the alarm system I suspect usually they have a -12/+12 output for this, I personally on my setup have two relays (One for locking, one for unlocking) these connect into the CL wiring on a master lock and are tripped by the alarm unit when requested by the remote control of course, this then completed the CL circuit and locks/unlocks the doors accordingly. This is the same as what putting the key in lock would do.

Martin

 

i was mearly correcting you on the 5 motors thing, the 90 spec onwards cars had the cable release boot/fuel flap which he will have (as he's got a 91 car) so he won't be needing the 5th motor

which has a different plug to the door motors

 

Sorry mate never realised that I thought it was an early model Saph I forgot he mentioned it was a 91 model, my appologies

Martin

 

so i am ok with the four locks.....and for the alarm i dont need anything more....?

 

Yes four motors if you have remote boot release, and I think it's alarm specific as they vary in there setup, as I say mine has two relays incorporated into the circuit others may not need it though, best to check on the alarm itself.

Martin

 

if you want to go with the ford c/l then there are 2 tyres of alarm that go with it, both work on curcits around the door locks, but these are seperate so you don't need to worry about them

the early ones had a horn that beeped when you locked them and a different box for the alarm depending on itf it was a high/low spec car

same with the 92 spec but they came with a flashing light rather than the beepy door lock to tell you it was armed

either way you don't need to worry as you will be looking for 90 spec onwards c/l motors with cable locks and the plastic anti tamper surround on them

90 spec cars also had a reversed open/close operation so that's anotehr thing to consider

 

i am ready to install the central locking
but car's manual doesn't say the number for the central's locking relay
for example the A is for the fuel pump
G for the electric heated seats
1 for the starter
2 for the lights

but it doesn't say the number for the c/l
and for the front electric windows
if anyone could tell me i would be very pleased!
me car is '91 1.6 cvh ford sierra 4 door!

 

what i want to say is if any relay is needed for central locking and electric windows or only fuses

 

No, neither the windows nor central locking use relays!

Martin

 

thank you very much!

 

does anyone know what is this for?it is behind the cigaret drop....near the lighter

 

I guess it has an aftermarket stereo, as that connector is for the standard item.

Martin

 

mmmm i think it something from sierra no from the aftermarket stereo....because a friend of mine who has a sierra with many extras(mine doesn have any...)has two such like this things....
what is the standard item?i can't understand it translating this to greek!

 

Thats what I said? It's from the STANDARD radio, so if you have an aftermarket radio then this won't be able to connect to, my guess is that it had an aftermarket radio as I said hence why it's disconnected.

Martin

 

a ok.....my bad english made me understand wrong....

 

i installed central locking succesfully due to your help!
thanks you very much!
no relay was needed!
just a fuse!
