More or less, by rewiring it with cables that ran around the machine on a cable tray shelf. It could take several weeks to connect all the cables for a specific problem, then if a mistake had been made either in designing the program or in connecting cables, several weeks more debugging it and making it run correctly. Also while testing and debugging you were almost certain to get a tube failure which had to be located and fixed before you could continue (the longest run without a tube failure was just over 150 hours, on average locating and fixing a tube failure took under 15 minutes due to replaceable plugable modules that could be swapped and repaired later). Programming also involved setting hundreds of rotary switches to select modes of operation, functions, and constants in lookup tables. Any of those switches set wrong also needs debugging.
