Pumps normally arrive without any bullet connectors, just bare black & red. Connect these pump wires, black to controller blue, red to controller brown, then the controller black & red to battery. You can use a chock block electrical connector if you dont have bullet connectors, 15amp will do £0.75p, just insulation tape up.

IF? they are jubilee clipped onto the barbs, you might want to have a couple spare in case they are knackered or you strip them (13-20mm).
If you look up spring controllers on the net you will probably find a diagram on their website if you get stuck.
