run speedwave 2640 without controller?

[roblarss]

pump side 3 pin connector with the dimple up is 24vdc right, gnd (-), left, 0-5v signal on bottom.

you should be able to test pump with low voltage between 0 and 5v on the bottom pin. 24v + is on right pin. common ground on the left pin for both.

This pump is same as the wp pump and has same pin standard...at least mine do.
