Check the date the console was manufactured or you can use this to help you: Xbox 360 hardware - Wikipedia, the free encyclopedia
When I first jtagged my console, I was completely confused as all the diagrams and tutorials I was reading were somewhat different. So for all the new comers here is a detailed guide.

Soldering Guide and Xexloader/XEXmenu installation Guide
Check List: (All these can be found at Radioshack or Ebay)
Buy:
Xenon xbox360 (needs dashboard 7xxx or lower)(8955 unable)
* 5x 100ohm resistors
* 3x 330ohm resistors
* 1 Meter of kynar wire (30awg wire-wrap wire)
* 1x old printer cable (the type that you can unclick the plastic end bits to change pin configuration of the wires)
Download:
* nandpro (http://dwl.xbox-scen.../nandpro20b.rar)
* dlportio (comes with nandpro)
* xenon_hack.bin file (rename to hack and put in nandpro20 folder)
* hex comparison (or a md5 hash program)
Soldering guide:
1. Solder in the lpt/jtag wires (picture below)
2.330 OHM (or switching diodes to make the currents move in one single line) make sure you keep those their forever, after you have made those connections time to bring out the 100 OHM
3. Note: On 4 you only need the connection going to the lpt, optional to add the extra diode.
4. Blue (2-1), Pink (3-2), Red (1-14), Yellow (5-17), Green (6-16), need to have the 100 OHM when making the connections. (If you are still unsure where the 100 OHM goes, the black rectangles on the colored lines (acting as wires) are the 100 OHM).
5. Time for the PC part of this tutorial.
PC GUIDE:
1. Make a new folder called nandpro20 and place it in C drive
2. Install dlportio (port95nt.exe in nandpro folder) driver and reboot the PC.
3. In the windows start menu click on run and type in cmd then press enter (opens
command prompt)(Run as administrator if vista/windows7).
4. Plug the power into your xbox360 (do not turn it on)
5. Plug the LPT port into the PC (make sure its connected to Xbox)
6. At the command prompt type c:\nandpro20\nandpro.exe lpt: -r16 nandbackup1.bin
7. At the command prompt type c:\nandpro20\nandpro.exe lpt: -r16 nandbackup2.bin
8. Compare with hex comparison (if files are different repeat step 6,7,8 until they match so you are sure of a good backup)(2 or 3 times should be good).
9. At the command prompt type c:\nandpro20\nandpro.exe lpt: -w16 hack.bin.
10. Remove the LPT cable from the pc and boot the xbox360 and you should have a blue screen with writing (if you don't, you messed up, and need to repeat step 9).
11. (Optional) unsolder the lpt\jtag wires but leave the ones with the 330ohm resistors they need to stay for life.
12. Place XEXLOADER or XEXMENU on the HDD or a DISK and run games, mods, etc.
XEXLOADER AND XEXMENU INSTALLATION:
Connect HDD to computer with transfer kit or wires
Open XPlorer 360
Open Hard drive
Go to partition 3
Your games are in Content\0000000000000
After downloading XEXMenu or XEXLoader place the files into Content\0000000000000 then plug it back into your xbox and it will be listed in Game Demos. (You might need to run it from a USB or disk) (You can use CD-R or DVD-R or DVD-R + DL to run XEXLoader or XEXMenu)
