Connecting Help - 12vDC Pump to Receiver

hey all, new around here..looks like a good community


Here is whats up:

I want to connect my 12vDC water pump to a receiver that will be able to turn it on 3-16km away with a handheld transmitter.

The wiring on the receiver is straight forward except for the connecting of the pump, I am unsure which is for which. The back it says, N/O, COM and N/C for each channel. The pump has 2 wires that are suppose to connect to the battery.

Which wires do I connect to the receiver? What goes where?


Here is a reference that may help, just to show you what i'm working with...
