hello, i have a 08/2nd gen tacoma prerunner 4.0 auto and am converting it to 4wd. i have trans and front diff to do the swap. has anyone swap the transfer case to the preunner trans instead of swapping transe? also has anyone made their own harness to make the 4wd work? I bought the 4wd tranfer case ecu and trying to get the wiring diagram for it. any help would be appreciated. thanks in advance.
