they may be 2 position relays
A is Out
B 12v in
C Out,  its the default position when not powered

then ground straight from pump or controller to battery

I have but I can't work out how to wire the pump into the a b c bit. Tried but just can't do it.   Can anyone please tell me in really simple terms.   It seems to click as if it is working but just don't know what wire go were.    Arrrrrrrrrr
Thanks.   Stu

The connections to the 12V DC - seems like you've done that as the clicking is the relay working.

Then:

Connect black wire from pump to the (-) on the battery.

Wire goes from the + of the battery to A.

Wire goes from B to the red wire from the pump.
