Step two: Install locking differential on transfer case.
Step three: Put "center diff lock" button in dashboard, wired to center differential on transfer case.
Step four: Push button to lock center diff.
That's how you do it. It won't do any good though unless you also install a front differential and CV shafts and 4WD suspension bits, and you'll probably want a driveshaft between the new front differential and the new transfer case.
Yup. It's just that easy. KidV wouldn't steer u wrong. Although the front driveshaft isn't necessary. You can use the rear driveshaft. Good luck and post pics!
