Xantrex LinkPro - relay wiring

I have a Xantrex LinkPRO battery monitor. It comes with a built-in relay that is closed when power levels are too low. I have read that the relay has been used for visual indicators, starting a generator, and various other uses.

I want to simply add a LED light to the relay.

The attachment shows the wiring, with A1 and A2 being the relay connections.

I believe I need to wire the LED to the A1 relay and then to the negative power supply (grey in the diagram). I think A2 is a second relay.

Does anyone have any experience with the LinkPRO to validate my interpretation of the required wiring?

A1 and A2 are the two pins of the relay. There is only one relay. Treat the contact just like a light switch. . To wire up a led. First you'll need a 12v led. ( or a led and a suitable dropper resistor. Connect A1 to twelve volts connect A2 to the 12v led . Connect the other side of the led to DC ground
