Here's what Bob had to tell me when I did the swap. It works in my truck, but I'm not sure if it will be the same in yours because of the year difference.
There are two pins at the T/C, one for 4x4 and one for 4x4 LOW. Which is which you would need to find out by trial and error. These pins go to ground when the mode is selected. So, all you need to do is run the 2 wires from the cluster down to the T/C switch.
Find connector C220a - it is the longest one at the cluster with spaces for 16 pins. Run one wire from pin 2 and one wire from pin 3 down to the switch, figure out which is which and you should be good to go. Just check to be sure that there is an orange/black in pin 5 of the same connector. It is the hot power feed for the two 4x4 bulbs and it should already be there because it also feeds a couple of other bulbs besides the 4x4 lights.

I don't have a truck like yours around here to look at but here's what I'd try based on the schematics:
- Go to the 4WD Electric Shift Control Module in the driver side rear corner of the cab. It can be identified by the 3 connectors going to it (two 8-pin and one 5-pin).
- Pick out the connector with 5 pins and unplug it. It will remain unplugged after the mod. In that 5 pin connector, the 4WD lights are controlled by the brown/white and gray wires.
- Cut each of those wires and extend the HARNESS SIDE of each down to the transfer case and connect them independently to the two pins at the 4x4 switch on the front of the manual case. You'll have a 50-50 chance of getting it right the first time. If the lights are not working correctly, just swap the wires at the switch.
