Mines a 05 and I put the fuse in the box under the hood like the book said and it worked fine, just made the 4wd light come on. the book said "only do this with the vehicle in 4wd lo in extreme offroading situations", so I guess it's designed that way. Just makes me appreciate the simplicity of my 71 CJ. Looks like I'll be putting some of Uncle Sams electronics training to use this weekend.
Thanks for the replies.
