When you say "pin (04)" do you mean parallel port pin 4 or BoB pin 4?
BoB Pin 4 is a limit input, connected to parport pin 13, and is an
input not an output.

Parallel port pin 4 is connected to the STEPY output, and I suspect
you need that for moving your Y axis?
(If not, then it probably should work)  It looks like the relay board
probably needs a 5V supply in addition to the logic and gnd
connections.
