Look this is easy, don't complicate it worrying about pressure switches, negative feeds and all sorts of other stuff. Your pump has two wires a red and a black. Shove the red to the battery, take a spur off the red to the red on the controller. Put your black controller wire to the negative (black) battery terminal. That leaves you a black wire coming off your pump unatatched, and a yellow/blue wire coming off your controller, unatatched. Join them up. Job done.
My controller has four bloody wires here, it's confusing the hell out of me. + and - to pump, and + and - to power.
Doing my tits in. The red on the pump connects to the pressure switch according to the vid Tosh put up, so I have to interfere with the pressure switch to join it up to the battery, this is when it stops working and does not kick in.
Has anyone got a simple wire diagram for a 4 wire controller? Before I launch the basta into orbit.

Yours is different to Cleancare with having 4 wires.
Let me get this right.
If you have + and - to battery and + and - to pump then the pump runs and you can reduce the motors speed hence the flow rate but the pump won't switch off when you close the tap.
If you disconnect the controller and use the pressure switch only, the pump goes like made but when you turn your tap off the pump switches off.
If I have got this right, then your pressure switch on the pump should be fitted between your controller to the pump on the + wire.
So your + wire from the controller goes to your pressure switch and the other wire from your pressure switch goes to the motor.Another thought. The Maplin replacement microswitch for the Shurflo pump has 3 spade contacts. The original has only 2 as the middle spade contact is removed.
If the pressure switch is working then the pressure switch will cut the power to the motor when the pressure builds up. The motor can't run without power.
