I just got this: http://www.efx-tek.com/topics/dc-16.html
Its a 16 output expander board. The Docs just say to plug in a red whte and black three wire cable but I'm not seeing where to hook these wires up to my basic stamp module. I want to be positive i got the wiring correct before attempting serial communication.
Anyone able to help?

I'd suggest putting a 220 Ohm resistor between the white wire and the I/O pin to protect the I/O pin from programming errors.
