This guide will describe how to fit a central locking kit to a 3dr corsa. In the previous guide the method used left the wires exposed, this guide is designed to show how to hide the wires. I used a cyclone kit but all kits are pretty much the same.

Tools
central locking kit
screwdriver
drill (10mm)
wire cutters and joiners

Steps

Ok first of all if you open your door and disconnect the rubber tube thing you will see the plug that connects the speakers. Pull the rubber back and check if you have lots of wires connecting to it (i.e more than 2) If so your car is already practically wired for central locking and you can use these wires instead of the wires provided with the kit. Here is a pin out of mine and the wires I could have used:





As you can see there are seven spare wires (The two circled green ones are your speaker wires) and you only need five so these could easily be used, however after unplugging the other connector, (the one in the door), I found that that was not fully wired and so I couldnt use it. You can ofcourse use it if you want to go and buy the metal pins and wire it in yourself however I couldnt be bothered so this is how i did it:

Take off the door trim
Just unscrew it all and take the handle casing off and black trim, to take the window winder off you need to get behind it and there is a metal clip you need to hook and pull off, then the handle will come off easily.

Drill hole
There is a nice unused hole that will soon be used to hold the solenoid, however first we need to drill a second hole.


Attach to lock
First put the metal bar into the solenoid, then screw it in and attach the bar to your lock


Mount box
I mounted mine under the steering wheel, the wiring loom holds it in tight and its a nice fit!



Feeding wires through rubber tube
Ok you need to pull out the rubber tube thing from the door, you'll see that the end where the wires go into it is very tight so i cut this bit off with a stanley knife


There is also a plastic cover on the inside, you'll need to pull this out and trim it a bit aswell


You can now feed the wires through and will end up with something like this:


Getting wires through connector
Right the only way to get the wires through the connector without actually wiring them up to metal pins is to drill a hole straight through it! You will need a 10mm hole to get all five wires through. You need to drill through the bottom left area to avoid the two speaker pins:



Pull the wires through and you will have something like this:



You will need to repeat this procedure on the connector in the door, to get this connector out you need to press all three points together and pull. It also helps to disconnect the speakers so you can pull it right out.

Connecting to solenoid
Now this easy bit, just connect the wires to the solenoid and its done. I also added some cable ties to keep the wires out the way of the window mechanism:



Connecting power
I wired my box into the fuse box. There is a gap already there for central locking, i just wired my box to it, put the fuse in and there we go, 12 volts! For a ground point i used the screw in the cover under the fusebox which screws into the body of the car.

Now for the other door
This is a bit annoying actually, you need to take the glovebox out,(5 screws dont forget the one at the top in the middle like i did:thumbs_up:) After that you need to feed the remaining wires round the back and over to the passenger side. The wires can now be placed to go above the glovebox like so:



Other than this its just a case of repeating what you did with the other door

Thats it!
Finished, took me a good few hours to be honest but the end result is a nice clean finish with no wires showing



The cost is just the cost of the locking kit really and a drill if you dont already have one

cheers:banana:

most central locking isnt remote, what usually happens is you buy an remote alarm, which has outputs/triggers to operate your central locking...

oh as a side note, i'm archiving these images and the tutorial onto one of my servers so as we dont have the same scenario as the other (rather good) central locking tutorial, in 12mnths time this one could well be dead and gone aswell....

*EDIT* - there ya go, in case the pics go down or something, theres a hard copy of it on my server @ http://dragon2309.co.uk/allcorsa/centrallocking/

yes, thats the idea, you buy the kit that comes with door actuators (master and slave) and the ecu that controls them... these on their own arent normally remote controlled... the remote part comes from hooking the central locking ecu up to your aftermarket alarm ecu (which you'd need to make sure has locking trigger outputs)
