You're right, I think the only difference is the diagram presentation... Everything seems to sync between the taco and 4runner through most years, only differences have been a few wire color changes and the different 4wd options/control boxes... The 80 just has 2 switches, is fed by a 30A instead of a 20A and the dash lights are the same 10A fuse...
I think I'm on it now... Thanks!
