Quoted from HighwayStarr:

installed mine last night ... pretty simple but a little tight as already mentioned ... ALSO as the video stated the "data east" holes shown in the instructions do not work because you cannot close the back box door at that height (it will hit the top of the color dmd)... Then when i dropped it down to the available next holes i still have to slightly lift the back box door to get it to clear but it works ... Seriously the hardest part for me was "Step 6" the tight space you have in removing the 15 pin CN6 and then installing the "power tap".... not much room to work in there ..... nice mod tho .. looks great and makes a big difference unfortunately I didn't get a lot of time to play and enjoy before i went to bed ...... off topic if you have the Pinsound Board this just makes adjusting that even more cumbersome but i guess those are the breaks and like BlackJacker already said definitely NOT a deal breaker .....actually if we could extend the existing 26 pin ribbon cable that goes to CN3 it would make accessing the lower part of the back box less frustrating ... I assume that would be possible by adding 26 pin ribbon extension to it but im not a computer guy ... definitely gonna look into it
