I've got a set up similar to rex's. I haven't gotten the bracket worked out yet to connect the locking cable to the cable going to the differential, though. It's connected, but not secured. I keep a pair of vise grips and lock it in that way, for the time being! Ghetto, but it works!

I've been inspired, now! I need to finish it. I'm tired of getting out and popping the hood every time I want four wheel drive.
