Mystery connectors under centre seat

Hi,

So not as yet come up against any real problems fitting cubby box in '97 110 300TDi Defender but I have got a couple of mystries to solve:

There is a multipin (with ony 3 wires attached) connector attached to the rail along the front of the seat (which I thought was the port for linking the "computer" for reading details off the imobiliser), a round 3 pin connector with a rubber cover on and a fuse holder with no fuse in.

They all go into the wiring loom that comes up from the transmission tunnel to the EGR unit.

Anyone suggest what they are / were for?

IMAGES NOW ON NEXT POST!

I'll get pics up as soon as I work out why the servers just chopped them off my OP.

probably the diesel control module Most peeps unplug it and throw it away Hence the unused Connector.

The rectangular socket in it's bracket at the front of the seat box is the diagnostic socket.

WTF are you on??? it's a 300tdi 110. What fecking diagnostics????

It's like the guy just said, it's a diagnostics socket. What the feck it's doing on a 300tdi I don't know but it's there. There's one on my 300tdi Disco as well.

I thought I had the mounted rectangular one sorted - it sunds like it is for the diognostics machine but only links to the alarm / imobiliser as far as I know (I assume hence only 3 pins used) to allow the data read off.

The guy definately went under the seat recently when he programmed up a new alarm fob for me. The round one and fuse holder are still unknown tho.

I'm assuming that was an extra?? That didn't get taken up very often?? Cos I've been in a few Landies and this is the first time anyone's ever mentioned a factory fitted alarm/immobiliser.

It could have been an option.

All the 'high end' defenders have them, if you are really posh it will also work
