Central Locking Wiring


First we will deal with the module and its wiring. Unpack your Universal C/L Kit and untangle the wiring. There is a set of 5 wires in Green, Blue, White, Black and Brown that are very long and branch off to 4 sets of connectors. The first two are a complete set of five. The last two only have the green and blue wires. It's these last two sets that will not be required and can be cut off at the point they branch from the rest. Insulate them so they don't short on any bodywork. You will also notice 2 short wires with bullet terminals that are brown and white. These are for connecting to the alarm and so need to be saved - just stick some tape on the ends for now and make sure there not tucked away. Finally you have your power cables - Black and Red. The red wire will be fused. This is the first pair we will deal with. Start by disconnecting the battery negative terminal.

I decided to store my Central Locking Module (the matchbox sized black box) in this compartment in the glovebox.

This is because it is easy enough to take a live feed and ground from the radio to here and the module sits in here very nicely without rattling despite not being physically attached. It is also reasonably accessible should I have any problems with it, and by using the passenger side of the car rather than the drivers side, I have more room to work in and less other wires to contend with. So I fed the wiring connector up through the bottom to the left of the heater/blower motor, pulled it out through this hole and connected it to the module, then put the module down into the gap and replaced the cover.

As mentioned, I took my supply directly from the radio circuit by removing the radio and splicing into the power cables. I then fed the cable down the void to the left-hand side of the radio where I could pull it through into the glovebox. The radio was then replaced. With the wire now in the glovebox, I fed it down the back of the glovebox out of sight to my module and connected it up.

Pull out the in-line fuse for the Central Locking Module for now and reconnect the battery.

Next to route the central locking wires. The shorter set of five will go to the passenger side, and the longer set to the drivers side. Firstly you need to undo the 2 screws holding the trim on the sills and remove the trim - this is so we can pull the carpets back. Do it on both sides. Pull the passenger side carpet back. The drivers side wont pull back without removing some other bits, but dont worry about that - you can work around it with the carpet as it is.

The passenger side wires will just go directly from the module straight behind the carpet so no worries there - we just need to concentrate on getting the drivers side wires over to the other side. Don't worry about putting them under the carpets yet - just feed them under the centre console first and then tuck them behind afterwards. Once your through to the other end of the console, you need to feed it BELOW the steering column. Theres a big rubber grommet there that will ensure the steering column doesn't wear against the cables, but prevents the carpet being lifted. You should still be able to feed it under and through out the other end without having to lift the carpet out. Then the carpet is held by the bonnet release handle. Again you should be able to feed it under the carpet without having to remove anything. Your set of 5 wires should now by out near the door hinge but on the inside of the car. Just tidy up now and be sure the wires arn't visible anywhere.
