I was looking at your write up and it looked like in one pic that it plugs up to the 2RZ fuse box that you used??? Is that not correct?
I didnt use the 2rz fuse box I just used a buss 6 circuit universal fuse panel with some bosch relay's for the fuel pump, EFI relay, starter relay and such.... I have a tacoma fuse box for it but there was too much crap in there that I didnt need or therefore want under the hood... at least you got it all figured out! you will love the power man!
