Balboa BP2100 G1 expansion kit

You will need these two cables if you wish to connect three pumps and a blower to your BP2100G1 control system.

The cable on the left of the photo includes a fuse holder for a 10A fuse for the blower. The splitter cable (available separately) on the right-hand side allows you to install two single-speed pumps in the place of a one two-speed pump.
