@ebzero89 - I upload two more pics of the back of the chassis..back1 and back2.. If I understand you correctly, I should not need to lift the pins on the jungle chip and solder where I just indicated on the picture label back1?You know if you can get the full schematic you can probably do this non destructively. A lot of the YouTube videos use the snipping and pull up method that removes the osd and so on. You don't have to directly inject into those pins is the point. Just to the non ground side of a resistor in line with the pin. MarkOZLAD on the shmups forums has a general overview schematic in his signature in the rgb mod thread there.
