If you are handy with a soldering iron, then it is not difficult. The pickup you have is a four conductor pickup. You have to tie the red and white wires together, and the green and the shield together. The black is your hot wire, and the green/shield is your ground. Tie the ground to the back of one of your pots, and the hot to the appropriate switch or pot. If you are not sure, check out Seymour Duncan's website for wiring diagrams. If you are not sure of your skill with the soldering iron, take it to a professional. It shouldn't cost more than $30 - $50.
