My Jeep has a low fuel light. What I want to do is have, in addition to the light, an audible warning buzzer that when it sounds, I can use a push to silence switch to override the buzzer. Anyone know if this can be done using relays? If so, how? Thanks.

You will need to get to the light bulb and verify that it is a 12 volt bulb.  If it is a 12 volt bulb you will need to get 1 wire to each side of the bulb and connect them to terminal 85 and 86 of the relay.  One wire to 85 and the other wire to 86.  This will energize the relay anytime the light bulb is lit.  Connect terminal 30 to a 12 volt power source, fused via a 5 amp fuse.  Terminal 87 will provide power to your buzzer or whatever you are using as an audible device.  Ground the ground wire of the audible device and you are set.
