well I recently did a explorer to bronco2 swap and i am now to the point of testing the 4wheel drive but when i push the button nothing happens no noise and no lights come on I noticed that when i pulled the harness from the explorer that went from the push button to the transfercase that it also went to the rear of the explorer and pluged in to a little black box does anybody know what that little black box is? and if that could be the problem

I know in my B2, there is a box behind the drivers side door. It'll click when I try to engage my 4wd. U might start w that box.

If you didn't change anything to explorer maybe check the fuse and relay but if you did check where the the B2 and explorer come together electrically.

That box is needed. When you push your 4X4 button, it sends a signal to that box which in turn sends a signal to your transfer case. Good luck. Let us know if you have any more problems. I just went through a whole fiasco with getting my case to work. Ended up changing the shift motor on the t-case.

On my '94 Ranger, if I pushed the button, it took quite a few seconds sometimes to light and kick in (dirty connections?)

You might drive around for a few minutes to see if it "wakes up" like mine did(?)
