Try to search for similar types. The pinout usually the same or very similar. Check GNDs and if match, you won.

I recommend pcix69000.
The only problem with ttl rgb driving is the max. cable lenght, that is approx. 50-60cm (20 inches). Over that size noise and crosstalk makes the picture wrong or the display is even unable to show the picture.
Skipping this problem, the card I suggested also contains a SIL chip, that provides a TMDS transmission at the same time, but in that case you need a receiver board (approx. 3x3 inches). The advantage is, that the supply of the display AND backlight and display data are in the same cable. Of course, you need a special cable also, but the max lenght is about 15ft.
