The Spydrx should have came with a pigtail that plugs into the only open port on the ballast and leaves 2 wires dangling, those 2 wires screw into the green adaptor that came with the ECS-2, that green adaptor then has a 3.5mm headphone plug that goes into it and produces a RJ-12 phone looking end, that RJ-12 end goes into a Trolmaster LMA-14 F lighting controller that you purchase extra, that LMA-14 F then plugs into the lighting line 1 (or 2) on the Trolmaster. From there is just adjusting settings within the Trolmaster for on/off/brightness/etc.
If the 3.5mm to RJ-12 cable is not long enough to reach the LMA-14F/Trolmaster, then you use the RJ-12 extension cable and RJ-12 splitter to add some length to the run by plugging the short RJ-12 cable into the black 2-1 RJ-12 adaptor and then the longer RJ-12 to RJ-12 into the other side and run that to your LMA-14 F which plugs in the Trolmaster.
