Jim, look at the pic in post #11. It looks like 4 relays connect into an 8 wire connector and the relays do not have individual connections.GGC,
If your system is like mine, any relay can be plugged into any port on the main card.
@Golferguycouple do any of your relay controlled equipment turn on and off properly? I only see one 120V circuit connected to the top left relay.
