I don't recall, if I ever knew, what the typical color
coding for a PS2 port dongle was. *You have vcc (power),
ground, data, and clock lines.

With a multimeter you can determine which pin is power by 5V
when the system is on (meter ground being system ground
anywhere). *With the meter the ground pin will have
practically zero resistance to case ground. *With data and
clock, if you get them reversed it won't work, just switch
the two around and try again.

Similar for the dongle itself, by looking at a pinout for a
PS2 port, you can use the meter to check continuity to
confirm which pins in the socket each connector pin
corresponds to.- Tekst uit oorspronkelijk bericht niet weergeven -

I don't have a multimeter.

So the lines are data, data ground, vcc.

Data, clock, vcc (5V), ground

(not necessarily in that order)



Should I connect it like this: yellow wire (data), blue wire (data),
red wire (ground), green wire (vcc)
Or: green wire (data), red wire (data), blue wire (ground), yellow
wire (vcc)

And the hole with no wire is for nothing?

The hole with no wire is for nothing, but I cannot advise on
whether to leave the other wires in the positions they are
in, or swap them. You need to determine which wires
correspond to which PS2 port pins on the dongle, and which
motherboard pins are vcc and ground. Without a
diagram/manual to tell you, using a multimeter is important.

If you connect it wrong it might damage a keyboard connected
to it.
