Normally you get an error 23 when, passed the initial test, the Lisa try to boot from the floppy (the first device available when the hdd is not present) and it do not find any floppy inserted on it. If during the initial test and after the first click you press any key eccept the Option key, the boot menu is shown. If you see 2 floppy icons, this is because the D/A8 Roms. These are Lisa 1 Roms, and Lisa 1 have 2 Twiggy drives. In your situation only Apple-2 can work. Infact, when upgraded to Lisa 2 with the 400K drive only the second flat was used and connected to the Lisalite board.

Is not easy to see without dismantle. Anyway the two cables are connected that connector in which the motherboard is inserted (looking from the back of the Lisa, it's that bigger on the left.
