Window washer - Power problem

Any ideas welcome --- Lost usage of the window washing pump a while back. It turned out to be a disconnected wire to the left of the clutch pedal (part of many wires join at a Security add-on box. Reconnected and all worked. Must have hit with my foot again and it disconnected again. This time when it was reconnected it does not work. Tried multiple times. Checked fuses and they look good. Looked for in-line fuse but can't see any. Don't have manual and can't trace back to the pump (Hate to admit it but I don't even know where it is...) Any help would be appreciated. Thanks.
