The KJ tow hooks are the same and you get two. I'm not sure why they only list one but if you were to order the jeep with them, it comes with two. BE CAREFUL not to use the "M" bolt that comes with them as they will pull out of the uniframe under the right conditions. There is another hardware kit available that comes with stud plates and the bumper needs to be removed to put them in. It's worth it. If you go to lost jeeps there's all the info you need on the subject, just do a search.
Not sure about the wires, the local uhaul had a pigtail in stock for that. You might want to check at the stealership to see what's available. I put on the mopar hitch and seven pin harness. It wasn't too bad to install. If you just want to run the flat one, the t-connectors work very well, I wouldn't let anyone tap or splice the wires as that causes problems later.
