Right now I can't face opening up the lid again to show you how it looks, but I plan to replace the backlight assembly quite soon to get rid of a scratch and a spot of dust, so I'll put up some photos then.
Until then here's an explanation of how it works, using other people's photos
In the image for step 7 here: http://www.insidemylaptop.com/replace-b ... 0s-laptop/
you can see the back (lid side) of the cable showing how the pins are connected.
Pins 1, 10, 13, 16, 19 and 20 are all ground, as is the criss-cross pattern.
Pins 2 and 3 are visibly connected and provide power.
Pins 4, 6, and 7 are to do with EDID: pin 4 is power, and 6 and 7 are data.
Beginning at pin 8 you have a repeated pattern of 2 pins, then ground: it goes R (8, 9, 10), G (11, 12, 13), B (14, 15, 16), Clock (17, 18, 19).
The SXGA+ pinout is quite similar:
Pins 1 and 2 are power
Pins 3 and 4 are ground
Pins 5 - 16 are the same R, G, B, Clock pattern you have starting at pin 8 of the XGA cable
Pins 17 - 20 are the EDID parts.
So you need to:
a) swap 1,2,3 to 2,3,1
b) move pins 8 - 19 to 5 - 16
c) drop pin 20
d) move pins 4 - 7 to 17 - 20
Which means that at the very least you need to cut the cable to separate 3 from 4, and 7 from 8.
... you need more cuts in fact, to make it easier to fold the cable to fit the new connector position.

shows the other side of the cable. There most distinct things in the image are - from left to right - three fat copper tracks and then a big gap.
The 3 fat tracks are the grounds corresponding to pins 10, 13, 16. This is great because it means you can cut down the middle of them to separate the cable, with lots of room for error and safe in the knowledge that any exposed contacts will be ... ground.
The "big gap" contains two groups of very thin wires: pins 8 and 9, and the 3 EDID wires. There's sufficient space to safely cut between the two groups.
After that it's 3 thick wires: ground, power, ground. You can cut down the two ground wires to separate the EDID group from the power lines (pins 4 from 3), and pins 2 from 1.
- Remove the plug housing.
- Looking from the front, where the wire tracks are clear, cut the cable to separate 3 and 4, 7 and 8, 10 and 11, 13 and 14, 16 and 17. Also separate 1 and 2, and 19 and 20 a few cm, so that you can shift 1,2,3 to 2,3,1, and fold 20 out of the way.
- You now have the following groups: power (1, 2, 3), EDID (4 - 7), R (8 - 10), G (11 - 13), B (14 - 16), Clock (17 - 19)
- Replace the cable in the plug housing, rearranging the groups as follows: power (2,3, 1), R, G, B, Clock, EDID. Twist each group 360 degrees anti-clockwise before you put it back in the plug, fold the EDID group clockwise. This makes the folding easier.
- Tape up the plug
- Set up the cable in the lid. Mark where the SXGA+ socket is. Tape the plug there, and then fold each group so that it lies flat.
I better post some photos.
