I'm upgrading from a 1-speed to a 2-speed Whisperflo today. I also need to add a relay to my compool to make the 2-speed work with the automation system.
-The 1-speed has 2 black wires and a ground, but the 2-speed 3 terminals and a ground. Not sure which wires go where.
-On the relay, I can tell where the small maroon plug on the relay goes into the board on the left, but unsure about where to wire the two red wires.
