Okay, My latest thoughts... Rather than risk damage to the display board connector, I'm going to buy a couple of 24-pin 1mm pitch through hole connectors, as pictured below. I'll use a short (2" is the shortest I can find) ribbon cable to run from the MAIN board to the first connector. The connectors will be mounted back to back and all pins jumpered (1 to 1, 2 to 2 and so on). Then I'll run another ribbon cable from the second connector to the display board. I can then tie in to the RGBHV and ground lines at the junction of the corresponding pins. This way the mod is also fully reversible. Another order to DigiKey Thoughts??
