For this code to work, you need to have the positive (red) lead from each solenoid connected to either the M+ or M- on the Spike (one lead per side). You also need to have both negative (black) wires connected to ground, preferably at the distribution block.

Actually, when i said FWD and REV pins I was specifically referring to the logic level (5VDC) outputs from the controller to eliminate the spike from the system at first. If you're getting the 5V signals, then you can work down the chain of command from there (5V signal -> spike -> solenoid -> piston -> mechanical action).
