Just a little extreme.
Man, all you have to do with that pump wire is test to see which one is hot when the ignition is on. Cut that wire and run both ends to the switch in your trunk.
The one that is hot coming from the front of the car will go on the (+) part of the switch, the one going back into the pump will be the (+ accessory) part of the switch and then you'll have to ground the switch to the chassis. Simple!
