Sneaky parts guy trying to clear his old parts out!

You might want to fab a cover of your own to keep water/ice off of the new part. I'd try a cut out from some smallish plastic bottle bottom. The bottle bottom would be the top of the cover...and a cutout at the front for the plug-in.

Is this what your using?... Most like it.

My truck needed the solenoid AND IWEs replaced to fix the problem.

Tool list and pics.

twfish, All the (this forum year group) 4x4s have the solenoid. All the 4x4s are "shift on the fly" (for 4HI only), even the floor shifter types. All the 4x4s have an electric shift motor on the transfer case.
