And here's the added parts needed to make it deal with the deadlocking and alarm.
I can't take credit for these instructions, I assembled them including the diagram from a variety of sources.
You will need:
- a single pole 12v relay (SPDT) like this one - the current rating is way above what's needed btw, but it has simple spade connections:
http://www.maplin.co.uk/p/12v-30a-dc-spdt-automotive-relay-n00aw- a diode (the thing shaped -->|-- in the diagram attached) like this one:
http://www.maplin.co.uk/p/1n4001s-1a-silicon-rectifier-ql73q- an additional passenger side central locking motor (you need to swap the driver's door motor which has mech deadlock for a passenger side one which is electrical)
Basic instructions:
- Remove the drivers door trim, the drivers side sill trim and the cover trim at the side of the throttle pedal.
- Remove the drivers central locking motor (you will need to remove the handle and whole lock mechanism)
- Disconnect the wires (at the bottom of the door - round plugs) to the two mirco switches which fit on the handle.
- THE WIRES TO THE 3 WIRE MICRO SWITCH MUST BE DISCONNECTED. DON'T JUST PULL THE SWITCH OFF AND LEAVE IT DANGLING IN THE DOOR.
- Fit the new motor to the bracket, ensuring it is as high as possible. When the mechanism is in the locked position, the motor plunger must be fully in.
- Fit a new terminal into the motor plug. This is a standard pcb edge connector, fitted to many fords, eg. to the old ford rectangular mirror switches.
- Connect this new terminal to black/blue wire at the round plug where the mircoswitch used to plug in.
- Re fit mechanism.
- Locate the central locking control unit in the drivers footwell. The new relay should be fitted close by.
- Follow the wiring loom that comes out of the drivers door and along the sill.
- As is starts to run along the sill to the rear of the car, remove the outer tape, and locate the 2 black/blue wires.
- Connect a new wire to one of these and then to the relay as shown on the diagram attached.
- Wire up as shown and fit the diode with the silver/black band side connected to the alarm. The silver line on the body of the diode represents the | in the ->|- in the diagram.
If you don't understand the wiring diagram, let me know and I can explain. This job takes about 1.5 hours - solder all connections and shrink wrap them or tape them (very well) for the best possible outcome.
