I just swapped an R150F 5spd manual transmission and transfer case into my 2UZFE V8 equipped 2001 Tundra and everything is working great except when I shift into 4wd the A.D.D. system does not engage the front differential.
Has anyone here done a manual transfer case swap and maintained the factory A.D.D. system and 4wd dash indicator lights?
After reviewing the EWD's of the 4wd systems for both a/t and m/t systems, it looks like the m/t 4wd systems just use relays to activate the A.D.D. system while the push button 4wd systems use a 4wd control ECU. I think it's possible to get something in place to make this work like factory but I'm guessing that someone else has already done this so I thought I'd ask before getting too far into it.
