Yes, this is a fairly simple procedure. However, I would recommend recruiting a friend or two just to make the job a little bit less scary-like when you are actually jacking up the body of your jeep on one side and it is tilted off of the frame. Two or more people just helps the safety factor for yourself and your jeep. Plus you can drink beer at the same time-haha. You should not have any wiring problems. With 2" you will need to install the radiator and exhaust drop brackets-easy, but the radiator is a PITA. The steering column is easy enough to deal with. You simply loosen a bolt before lifting and the shaft will slide out and then you tighten it back up when the lift is complete. This is definitely a do it yourselfer.
