[urq] G'box numbers, Areial wiring and more

After a fairly long period without posting I now have four questions:

1. Aerial Wiring: I have been fortunate and obtained a fully working original electric aerial for my WR. The wiring feed to it appears to be a two-wire T-shaped connector with one spade connector set at 90 degrees to the other. The top of the "T" is a red and black wire which appears to be a permanent live (from where I am not absolutely sure but a continuity check suggests it comes from the radio - but perhaps changes colour on the way). The vertical of the "T" is a plain white wire which definitely comes from the Radio and seems to be the "trigger" feed from the radio (I know this because I have tested continuity of this to the multi plug on the rear of the radio. (I call it "radio" but it is a Blaupunkt CD & radio). When the t-connector is connected the aerial will not lift or retract when the radio is switched on. Nor if the ignition is switched on. Makes no difference.
If I touch the red/black wire on the "aerial" terminal for the white wire, the aerial lifts. If I touch the red/black wire on both terminals simultaneously, the aerial retracts. But if the two wires are connected as they should be, nothing happens.
Does anyone know what is going on and how it should be wired and should operate?

2. I have a spare ECU which has the pressure sensor outlet "stump" broken off. Does anyone know a supplier of this sensor (transducer) and if possible a part number or value/rating. Approx cost would be welcome too.

3. Can anyone point me in the right direction for a chart or the like to show how to identify the various ur quattro and coupe quattro gearboxes. I have an 016 gearbox that came from a one owner from new 1986 coupe quattro. I also have what I was told was an ur quattro 016 gearbox. In almost all aspects they seem identical (only difference I have noticed is one box has a switch in a different place where the other has a blanking plug and vice versa. Is there any way to tell what boxes I have, and what ratios they contain. I always believed the coupe quattro was lower geared than the ur quattro to give it a bit better accelleration with its lower powered engine. If true then it will be no use in the ur quattro.
I know that the numbers on the top of the bell housing will tell you when a box was made - i.e. 20106 is 20 October 1986 but I would like to know more and ultimately confirm what I have in these two boxes.

4. Finally, the sender that sits in the hole on the top of the bell housing - that looks for the pins in the flywheel - how do you remove it without breaking it. I have removed the cap screw and it is possible to rotate it in either direction but I can't lift it out. Any good suggestions.

I will be grateful for answers to any or all of the above questions and will look forward to reading the. 
Many thanks.

I guess you can tell from the length of this email that there isn't much to here because it's STILL RAINING here in sunny (a long time ago) Worcestershire.
Have a look at the galleries attached to these links if your interested. We have had a bit of bad weather here recently to say the least.

Still 175000 people with no (clean) water or electricity. 1000's flooded out of their homes. 

But it's going to be nice tomorrow!

All the best
