Wiring/Testing a relay

I have a relay with 5 wires for my fuel pump. Its the fuel pump relay that come with the DFI. I have it hooked to a switch on the power side going to the pump so I can cut the pump off...but the relay will still be powered.

Will this burn up the relay?

How is it wired and how would I test one? I searching for how to test it and had no luck for the most part. But I think it is bad I swapped relays and it works fine. But want to know how to check these for future ref.

has 30 87 87a 85 and 86 on the diagram....

I found this...the 5th wire is confusing me.

The extra terminal is for use in making a connection when the relay is not energized. It gives you another option.
