Hi tomcat59alan, hope you are doing good man. Do you mean the large circular connector under the expansion tank? I have examined that connector and from what I could see there is no corrosion, and the wires I checked for continuity were fine.
 
Mine were not circular mate, i had to cut into the loom where I found a brown wire that feeds power from the yellow plug under the fuse box to the obd2 plug had rubbed on a brake pipe.the car in question is a 1994/5 so yours is probably different. I'm doing ok thanks,just tired, she's had me busy today.good luck.;)
 
This can only be a faulty connection from throttle pot to ECU. A faulty throttle pot or a faulty ECU. As the feed from ECU to the diagnostic plug uses the same two wires as other systems that are working.
 
Mark hey there, the Diesel Injection Pump, personally I have not touched the pump, it might have been done by previous owner.

I had an ex-Land-Rover mechanic out to look at it a few weeks back, and he mentioned that it could be the module on the Injection Pump, and that it was a 'pump out' job

Does the head need to come off to change out the pump? I think he mentioned that its not so bad once you have the timing chain tool.

Right now, the car is stuck in low range, so the auto-sparky is going to look at that and then the EDC ecu comms issue.

I guess I'll let him at it, and if he doesnt get anywhere, then look at the injection pump.

I find it hard to believe it is the injection pump, you are looking for a bad connection from ECU to OBDII socket. As said earlier the wires that feed the OBDII socket from the ECU also feed other systems that are working.
