It might be a good idea to put color codes like on a resistor on the connector plug. You know, green for 5 gold for + center pin and silver for - center pin.
No gold or silver band would be AC.
Brown Red Gold would be 12VDC + on center pin.

Poor thing didn't stand a chance.
You'd have thought that after all these years, some sort of keying
system would have been developed, but I guess not.
