From memory all '30' terminals have battery voltage on them all the time. The control system (there are several) will pull in the relay to energise whatever may be on the end of the output wire - ie fuel pump.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?
