Solved OBD2 Connector Issue
My OBD2 Connector under the drivers dash was dead. I tried cleaning the connector with electrical cleaner, making a new ground and even back probed the purple power wire which illuminated the code reader but didn't down load any data.
I went to the passenger side and pulled down the trim under the glove box and observed a large typically English sloppy bundle of wires that are part of a larger harness. After removing the tape and exposing the wires, I observed a large amount blue corrosion dust that fell out of a yellow connecter that is a actually a distribution junction for six purple wires bound together. I noticed that one of the smaller purple wires in close proximity was broke . I probed the junction and found the purple wires were hot even with the ignition off. The broken purple wire was downstream and carried no power.
I stripped and extended the broken purple wire and back probed upstream side of the yellow connector with purple wires and the OBD2 connector came to life posting Code 441 Evaporative Emissions-no big deal.
This is a common problem on the this forum: inoperative code reader connector. It's a relatively simple procedure to fix. Cut right to chase by going directly to passenger side, open that harness under the heater blower motor, find six purple wires tied together in a common yellow connector, and trouble shoot that area it's either a severed wire as in my case or perhaps too much corrosion it the yellow connector itself.
For some reason merely back probing the purple (power wire ) and the brown (ground) on the connector itself will only illuminate the scan toll but not download data to the scanner.
Thank to all others who contributed to this solution. I hope this helps somebody else.

"This is a common problem on the this forum" ........................ NO, it's actually a rare occurence if the truck is looked after and maintained like any truck of it's tender age, but what do you expect, a new truck for a cheapo price and leave it to condensate and rot for years .................. get a life eh
................. or some old US rotting heap. It's a pity you trashed your very good write up with factually incorrect silly little racist statements

"large typically English sloppy bundle of wires" ................ you bought this old probably 6th hand well abused truck eh, just buy some American rust heap instead.

No offence intended
When I posted my resolution of the OBD Connector Problem it wasn't my intention to offend anyone. I just wanted to give back to the forum. When I made the comment about the typically English bundle of wires, I was referring to an observation I have made in owning several English vehicles including a Jaguar and a Triumph TR7 previously. It appears that the wiring is simply not to the same standard as Asian, German or American Vehicles. For example I own two BMWs and the OBD 2 connectors are doubly protected from corrosion with both a cover trim piece and also a plug to keep moisture out where as my Discos is just pressed into a piece of plastic under the dash with no plug.
I love my Disco and have taken good care of it. I don't know how a lack of care on my part could have caused this problem. Who periodically checks wires under the dash? unless there is a problem. The very fact that this problem occurred basically proves my point about the wiring on these vehicles, I have never owned a vehicle where the code reader went out because of moisture getting into a harness under the dash. Does that reflect thoughtful engineering?
When I had my TR7 I couldn't keeping running because of all Lucas Electrical Problems so I finally gave up. It was an excellent nice looking, good handling car that's why I bought it but the electrical was so bad. Likewise with my Jaguar.
People tend to take the most offense from comments that have a measure of truth in them.
In regard to "racist' I don't think the word "English " denotes a particular race per se. We on this side of the pond who don't curtsey to a monarch tend to express ourselves more unabashedly and aren't so intense that we get upset from a mere glib comment.

British autos from this era and earlier weren't exactly known for the quality and reliability of their electrical systems, though the DII is relatively well sorted in this area.
It's not a rare issue, it's come up a few times on this forum and DWeb. So common, in fact, that on the rare occurrence I'm at the dealership for service that they'll bring up preforming a "courtesy" OBD connector inspection service.
And finally... I don't think racist was the word you were looking for.
