You mean a module in a MGB?  No, I've not, but if you like, I could throw a diagram together showing how to install it?

I may also make a diagram showing how to install without cutting the traces.

Edit:  It may be a good idea to replace the diagram you have on the website, with the one I created, as the one on the website has a mistake in it. (I discovered this the hard way when I was modding my first MGB)

Not yet. I see no reason why it shouldn't work though. Did I make a mistake?

Updated the diagram. Made a mistake. the VCC point was wrong. Turns out you have to use the point on the otherside of the motherboard. Tested it today.

Ok, another quick update to the diagram after doing some more testing.  Found a better VCC point, which now keeps all wires on 1 side of the board.

Also worked out that grounding the 3 pins on top side of the chip can cause the screen to randomly turn ultra dark.  I'm assuming on the module, only the one pin on the end of the chip is grounded?

So yeah, if you're biverting a MGB, make sure to only ground the one pin on the end.

OH and lifting the pins on the chip is ALOT easier than trying to lift the pins on the LCD connector. Just be very careful.
