2wd 4wd dash lights needing wiring for 2001 Prerunner 4wd Conversion

I just purchased a 2001 Prerunner DC Tacoma that had been converted to a 4wd. I would like to wire in the speedometer cluster indicator lights for 4wd. There are three switches on the transfer case (J shift TC) that have empty connector leads on them (2 are on the driver side and one is on the passenger side. My local junk yard has lots of 4 runners with the same connector leads coming off the transfer case but the wiring appears to join into a very large main harness. I'm looking for some help or ideas how I can hook up these switches and create a new smaller harness direct to whatever fuse box panel location they need to go to. Any help would be appreciated.

 

Is yours the j-shift or the one with the button in the handle for 4H?
