Gonna necro this thread. i just removed my pinbot back box and while it wasn't terrible, it certainly wasn't a walk in the park. at a certain point, i ended up having to unhook several extra connectors due to one or two wires being added to that connector and then going to another, and then another. also had to cut the wires to a solenoid so i didn't have to remove the fitting that held it in place.
i've also got an earthshaker, which is system 11 B. anyone know if these are any easier to remove? from a glance, it looks a little less convoluted, but then so did pinbot at first....

update: ES was WAY easier to remove than pinbot, even with the ES having had some wiring work done to it by the guy it bought it from. looks like it was designed to be easier.
i would also recommend using blue painters tape over electrical tape. electrical tape is one of the worst things ever created. just hate the gross residue it leaves after you take it off.
