I thought I'd start a thread on the connector pinouts. I don't have all the answers, but I've got the USB and the TV-Out Video cable (SAMTABRCA), and I've beeped them out.
Since this is a non-standard connector, it isn't clear which end is 1, so I've chosen #1 to be the farthest left pin as you are looking at the connector with the Samsung logo up.

The ground pins are all connected together, and are common between both cables.
It appears that pin 18 on the video cable tells the TAB that there's a cable connected?
Pin 23 on the USB cable doesn't seem to be connected to anything. It's probably too much to hope that it is a USB to go pin, although a floating ID pin indicates a device, while a grounded ID pin indicates a host...

Well, I had a 50/50 chance...
Figures I'd get it backwards!
Now we have to figure out where to get the connector! Neither Digikey nor Mouser have this one, just the backwards iPod one! I've got an iPod connector that I got from Spark Fun, and the only way that it might possibly work is with an exacto knife.
Does the car connector or HDMI dock have any writing on the connectors?
Also, not sure what the USB +4 is? Does it connect to a USB pin? Which one?
CAR dock have numbers on PCB where connector is soldered.
USB +4V is maybe +5V (I measure voltage and find 3.98V)
and maybe this is not for USB ?
Maybe this is power from battery for supply external components ?
Power from USB Host (or 2A 5V power supply) to charge is connect to 7 & 8 pin.
I think TAB send MHL digital video/audio packets to HDMI dock and dock convert it to HDMI (I found Silicon Image Sil 9290 chip inside HDMI dock).
Next chip inside HDMI is micro controller 89C58RC from SST(for control Sil 9220)
Next chip is DC/DC converter 5V->3.3V for supply chips

I'm bummed about pin 8, though! I was hoping it was USB-to-go, but clearly it is there to take the current for fast charging. <Sigh>
Although I'm curious about the USB connector on the HDMI doc. Any idea what can plug into it?
When I mentioned writing on the connector, I was hoping for some sort of part number. Guess just the pins are numbered. I think that getting a connector is going to be tough!
USB is for Computer connection and for Charging
USB data lines is normally used under "USB setup" to set usb high speed or low speed mode. This is just set using pullup or pulldown resistors. Many devices that uses USB for charging uses the datalines in the charger too. Like GPS's I've seen also has a pullup on one of the datalines in the charger to tell the device that it is connected to a charger only and not expect a data connection.
On some devices it also tells whic charger mode. High current or low current charging.
For pin 13 we should try to go into the source code and see if there is anything that can catch a glance of what voltages it expects (values) there for different mode selections (if it is open at all and not just a precompiled lib).
Or if it is possible to make a program that can force the Tab into deifferent modes by overriding the reading of this analog input.
We should at least make a table her on different voltages/resistance for the different modes.
Only source I've seen is WebKit and the kernel. It's possible that there are clues in the kernel, but I'm not sure how likely that is.
I just tested som things here at the office today.
I took the original car holder and modified it a bit.
I soldered in wires and a 3,5mm stereo jack to get audio output without the need to plug in more cables on the holder.
I soldered the wires to pin 30(gnd),28(Right)and 27 (left)
At first try nothing happened....
The solutions to get audio out there is changing R2 from 1,6Kohm to 6,8Kohm's.
Then the tab accepts this as an audio output instead of a passive car holder.
So now the holder works better for me.
Nice findings, hope this helps:
Here some huge photos off the tab dismantled from ifixit: http://www.ifixit.com/Teardown/Samsu...eardown/4103/1

Will be nice to find in the source code any related info about the controler, in the galaxy S Thebeano find something about the microusb controller to put the mobile into diferents modes, with resistors.

Now I have been checking a bit more in the source thanks to TheBeano's findings on the I9000.
This is the list of stuff it detects on the port.
It is detectede resistance between ground and ID pin.

I will try to find the correct values for theese modes as well.
This is from TheBeano in the I9000 thread:
Here is a list of all the resistor values, from fsa9480_i2c.h in the open source code for JPM. The resistor goes from pin 4 to pin 5 of the micro USB plug (full details on how to wire this up are in this thread (http://forum.xda-developers.com/showthread.php?t=819551)). When you connect the plug with the resistor (in Froyo) you should see some messages from the fsa9480 driver in the kernel log, which you can view with the "dmesg" command.

How did you read those data?
I am looking to hack a GTab together with an Arduino to make use of several different sensors, and am trying to figure out how to read that data. Could you give some pointers on how to make it happen?
PS. I am kinda new to this hacking part of Android, but am experienced in coding it in java.
Galaxy Tab Conenctors
Found a website that has Galaxy Tab Connectors:

WOW, it has JTAG TX and RX, nice..
anyone realise the original htc charger charges faster? especially now with those 4xusb port chargers.
i just did a simple test
test1
4xport 2ah + original htc cable = 150+mah
original charger + original cable = 800mah
test2
4x port 2ah + seagate dual usb cable but pluged in the 'power' cable + mini<->micro converter = 150+mah
original charger + same cable as above = 150mah
test3
4x port 2ah + seagate cable but the data usb head + mini <-> micro converter = 150mah
original charger + same cable + converter =800mah
i believe that the data pins are also supplying power aka pins 2 and 3.
i'm going to test pins2 and 3 with a multi meter when i get back to office.
i have tried 3 different brands of 4xusb chargers. only one of them charges @ 800mah.
please note that the hd2 implies constant voltage/variable current charging algorithms. This means that for a constant charge voltage of 4.2 volts, the charge controller will draw more current if the battery is at 10% then if it's at 90%.
Also, take note that the hd2 has 2 charging modes. The charge controller takes about 850-900mA at max. but as a standard usb port only supplies 500mA, the phone "senses" if it's plugged into a usb port and lowers the max drawn current to anywhere between 100-400mA in order to protect the usb port. The switching between the 2 modes is made by the presence of the usb data pins. If a voltage of about 0.9 to 1.7 volts is present on the data pins and GND, the phone thinks it's plugged into an usb port and will never draw more then 100-400mA. In order to charge as fast as possible, you need to apply power only to the Vcc and GND terminals, without connecting the data pins from the phone (2 and 3) to anything
Sent from my SGH-i917 using XDA Windows Phone 7 App
ok, tested, i soldered pin 2 and 3 on the charger. hd2 is now drawing 900ma
that's the most you'll get from it
