Well I didnt cut wires, I saved all and sold everything as a package. So first day I removed all large boards and wires and the individual leds. Had to wait on some fish paper since i only got 4 pieces ( could have used electrical tape but has other things to do). Replaced each large board as I removed, used the map or wires and guides to position new single led boards, used the dimple tootl and drill holes and mounted. Going in ordeer as I removed and labeling new boards with sharpie.
Second day was removing and replacing boards in castle playfield and munchkinland. Not hard, take your time and dont force anything. Hardest part was getting all the new wiring down the holes while lowering playfield and not trapping anything underneath. The raindow board is the worst. They do send new plastic rivets but do not send new rubber push through washers that attach the board to the plastic with the black filter sandwiched in between. Would have some of those on hand before you try.
Third day fish paper arrived, finished the single led boards that require that and the ran started running rgb cabling. The cables look very similar and the inventory drawing is a small picture and hard to tell. Follow the diagram to see how many leds are connected to each string and count the connectors on the strings and you can figure it out. ( Would be nice if they were numbered).
Last are the Cat 5 cable and they are simple. The directions are pretty good. Would add that when you get to the step of removing the toto lane and haunted house cable, it says to leave the cable in machine as this will be used. This isnt that clear, but you will need tomake sure you have some play to be able to run cable to the WOZ7 board in the lower left corner ( playfield upright).
I would say total hours was 12-15.
