Dell Precision, help w/ internal card reader ps

[lappyhappy]

Just installed a card reader but I'm not sure if I plugged in the power to the right place on the board. Has anyone worked with one of these that could verify for me?

The power cable has 4 wires attached and I plugged it into the board where it says "usb" and has places for 5 pin and 4 pin plugs (obviously I plugged it into the 4 pin one.)

Pics...

In case anyone else sees this and has the same question...

I found a schematic of the mb and it is the right plug so all is good...
