    Hi everyone! I’m new here. Just bought a 2004 Tacoma automatic with J handle shifter transfer case. 4wd light was flashing when I bought it. Found ADD was damaged and fuse blown. Also found a 4wd ecu under the seat which makes me think they were trying to fix it. Replaced ADD and fuse. No change. Tested transfer case switches and the work but seem to have a lot of random resistances. Testing at the connector to ecu but can’t find wiring diagrams for this unit. Seems push button one is more popular. Any help would be appreciated.
