Hi All,

It looks like 4 of the wires should be connected to 4 pins on the Mega. Good luck.

If you posted a link to the device (not to ebay), perhaps we could even tell you where to connect them.

TX to RX1
RX to TX1
UCC or VCC to 5V
GND to GND
then use Serial1.something (read/write) for communication. If your board is 3.3V TTL logic and not 5V logic, you can not connect modem to 5V Aurduinos (you may be lucky with Arduino Due).
