The four pin connector (4 in a row) is almost certainly a USB compatible single port for a typical card reader. Most motherboard connections for USB are for dual USB ports, with two rows of pins. The guide for your model of motherboard should help you decide which 4 pins to connect the single port cable, to one row of the two-row pin header probably marked as JUSB2 is likely. The direction/polarity of the connector when attached, and starting pin position are important pieces of needed information. JCOM1 is an older serial port... not common for card readers. JTPM1 is unknown, JFP2 is probably front panel ports for either audio jacks or power/reset/or LED functions.
