You can also remove the vsv for that vacuum canister, one of the lines came from the vsv into the canister.
I made some brackets out of some aluminum stock I had, made a template out of thin cardboard first:
Then cut them out, shaped them better and drilled the holes. Here is how they turned out (I'll probably powder coat them black later, I don't feel like getting my pc crap out just for those).

oh for the o2 sensor i ran the other black wire to the black/red ignition wire...hopefully that one is ok. pin 71 and 48 had pins from the old ecu, a brown and a yellowish wire..i just unplugged those and pit in new pins for the blue and 1st black wire. i need to find out what those are, in case theyre important. especially if thats an ecu ground. granted the new ecu is being used for what those pin spots were meant for, if whatever the yellow/brown wires are attached to still need input or ground from ecu i should fix it.

ok my problem was looking at the wrong ecu pin out. jza80 GE ecu is different than a jzz30 GE ecu. those other wires are just the old O2 wires

To update I tried starting my car today to no avail, I will be double checking the wiring this week.
I confirmed my IGT is white/green wire at the ecu, but my "tach" wire which is a pale green connects to pin 20 NOT 16.
I also found the pale green wire on the cruise control plug which leads me to believe it is the tach but just not in the right spot?

i have a question about FFIM and IACV and how that could affect timing. Since I have no IACV i have the TB cracked open to compensate, meaning the ecu is going to read throttle is open when i do the jumper for timing. Should I then have my TPS set at 650 with TB fully closed or should i set it at 650 when i have it cracked to get proper idle?
that said is there a way to adjust timing without starting the car, and just manually set timing from 10 down to 6~7 and bypass the jumper business?

p.s. here is a pic of where im at; TB and FFIM installed, im about to go back out and turn the key to the "on" posistion and see what works/what doesnt; prime new fuel injectors and see if theres a leak...or worst case if something decides to smoke...
Q45 TB is such an odd diameter tried all different sizes of coupler, went with one thats pretty snug, better than loose. stupid t bolt clamps wont fit it either, had to use an ugly clamp. still need to fix all the vacc hoses and IC pipes and get the IAT installed somewhere, so it will be a while before i can start it. that throttle cable is so close yet so far. im going to have to make a short extension.

So basically what i got is the green wire is Te1, was at the igniter and not the taco wire.
Can I move pin 20 to 16 or do I need to run a new wire for the taco?
Edit looked back at the first page which were i can see the Te1 and tach coming from E28. Whats happening there?
