Took some time today to remove the electric shift harness and computer and then stripped it down and modified it to get my dash 4x4 lights to work properly. The Ranger harness is different so I had to make my own instead of just getting the donor Explorer harness. The lights are turned on by a ground signal and are run through the shift computer which means the harness has to be chopped and modified. I have never seen a write-up on adapting the e-shift harness to the manual for working dash lights but here is basically what I did.
Remove driver seat to get to the plug through the floor. Disconnect gray connector under center of dash and remove entire harness. Cut the shift motor plug off and remove all the electrical tape.
Remove red piece in grey connector with needle nose pliers to access the pins. Use a small pick to pry back the lock tabs and remove all but the 2 wires you can see in a photo below. Reinsert the red divider.

Cut and splice them to the wires going through the rubber plug. An off-white one and a brown with white stripe. Cut all the extra wires off too, you don't need them. I left 3 wire pigtails for future use since it is a nice pass through grommet.

My ranger case had 2 blue wires to the shift indicator. I spliced the solid color wires to each other and the wires with stripes to each other which got me the correct lights working. Test first!

I wrapped the in cab harness with electrical tape including the tabs for the mounting screws and the underside with loom and then tape.

The leftover trash pile not including the shift computer and most of the big harness to it which I pulled out later.
