I wired mine with a direct feed from the battery to a remote fusebox, then to a relay, then to the pump. You can energize the relay either with a toggle switch or ignition key. Here's the type of relay you need: Just an example, you can probably find a cheaper one.
I reused all the original wiring and jumped the computer wiring and added a relay (at the computer location) to turn it on and off with a switch instead of it running as soon as you turn the key on. I wanted to retain the rollover switch in the back just in case, plus all the wiring was already run to the pump from the factory.
