Lucas 10AS connectors

The Lucas 10AS unit is used for a few functions in various Land Rovers. It was the standard immobiliser and alarm for many years. It is also used to control the interior light so they fade out. In some models it controls the central door locking.

I plan to add central door locking and I would like to use the original style remote controls.

The first step in achieving that is to rig up a test setup for which I needed some connectors.

These are a standard component, still in use. They are from the TE Multilock range and use the 040 and 070 terminal sizes. All of the Multilock bits together came to less than £10 from RS Components. I bought the OBD socket from e-bay for about £2.

The RS Components and the manufacturers part numbers can be seen in the photos.
The manufacturers parts numbers are:
173851-4 Green connector housing
174516-6 Grey connector housing
173631-1 070 crimp terminal (for the green and grey sockets)
173716-1 040 crimp terminal (only for the grey socket)

The last digit following the dash for the plugs, indicates the colour; -6 = grey and -4 = green.

The idea is to rig up a test loom so I can check the function of the door locks without dismantling the dash and crawling round inside the car until it is all working.
