Is this correct for the relay wiring?

Looks good to me.

Number 2 should work.

On a relay... a relay is basically a magnetic switch for higher power items to be controlled by lower power switches etc.
Pin 85 is typically grounded. This is a good place to put a switch. If the wire for the ground that comes through a firewall etc gets rubbed...the worst that happens is the item controlled by the relay is running.
Pin 86 is typically an ignition based power, no need to be a high amp fuse, it's only actuating the relay magnet. When this is an ignition based power, your item will not be able to run w/o the igntion turned to on. When they key is turned to off, the item will automatically turn off.
Pin 30, this should be a fused power sourse for operating your IC pump etc.
Pin 87 this is the output pin. Therefore when the relay is actuated this is the pin that leads to your IC pump etc that needs power.
If you have a relay with pin 87A, 87A is connected to pin 30 when the relay is not actuated, This can be used for a variety of other instances etc..
If you have further questions of how or why relays or basic electronics stuff works, I've found the12volt.com in their basic area to have some of the best explanations for people that don't already understand how this stuff works. I've used it many times.

Replying to this since it's somewhat recent. I bought a five pin relay and pigtail. Trying to understand this
Pin 87- wire black..will wire directly to pump harness power wire red?
Pin 30- wire white will connect with 87a(red) and connect to positive post on battery
Pin 85- wire orange could wire to negative post on battery?
Pin 86- wire blue, should be fuel pump fuse panel.
I think I lost something here. Should have power in, power out. Same for negative and the switch. Where do you ground the negative wire on pump harness?...

Thread bump. Where do you get this relay for an IC setup?

You can purchase them from parts stores, Radio Shack even Wal-Mart usually has them, HOWEVER most of the time these relays just have "blade style" terminals sticking out for you to connect the female connector to. If you are going to install the relay anywhere outside of the cars interior I recommend using a relay with a sealed "weatherpack" connector. You can order these, but I just get them from the junkyards. You will have a sealed connection and they will look factory as well.
