Once I'm fully tuned and am 100% satisfied with the tune an feature, I plan to either do this and eliminate the PnP harness o just have fresh harness made.
On a side note , I couldn't get my ac request switch in car to turn on ac . I inverted signal within ECUMaster , ac clutch activates . Tech support was able to set it up correctly within my calibration and now works perfectly
Please post results once completedn

update: i finished pinning EVERYTHING would not recommend it took me something like 12-14 hours to make all of the wiring changes. It was nice to have an auto harness and re-allocate some of the wiring for sensors.
I basically went through the pin sheet they give you with the PNP and did those first, then i serious had like 20-30 wires leftover that just weren't used in the PNP lol, i just taped off each one labeling the best i could and tucked them in some conduit because it might be useful to have extra wires throughout the harness later. Having the right crimper made quick work of swapping to the new pins. I had two leftover uncrimped pins from the ecumaster box. I also pinned it so the ecu will have constant 12v power and the ignition is 12v switched, the pnp bridges those two together and the ecu never has constant power. This will allow you control over the IACV parking and some other stuff like delayed shutoff if that is wanted.
Advice for someone looking to-do this: add more wire to one of the ecumaster plugs and stagger them more as mine were pretty close and STUPID hard to get down the wiring hole. Also my ecu doesn't sit in the same spot due to less wire length but no biggy ill modify my bracket.
I now totally understand why the fancy harnesses cost $1800. Much respect to those guys.
Put the harness in the car and tested, seems like everything works that did before but i wont know until i get the engine in.
My tach still doesn't work when i test it so idk what to do with that, @lexforlife how did you wire up your tach? I used pin 8 on the Orange plug down by the kickpanel area.
Stay tuned for a video i did some timelapse of this process.

Props on the harness work. I don’t know if I’d have the patience...

Did it show no RPM prior to doing the resistor mod?

Shifter is temporary as it's the only one that fits. I need an adapter to fit the GR leather one.
Pretty sure the auto cars have a tighter tunnel or something, or the supra tunnel is larger than the SC. that bolt missing there hits the tunnel, I ended up throwing shorter washers on it.
What i may end up doing is getting a regular bolt that's a better length for that hole.

The other side had a unused tab off the trans that was close to the tunnel which i was able to dremel away.
Now im thinking about it again and i probably should just bite the bullet and take the bolt out and go get a shorter one that doesn't need as many washers. UGH

I ended up getting a slightly shorter bolt from Ace and used a dremel to round down the head of it a bit. Gained a little bit of clearance i think it'll be fine/self clearance. Next time i have the trans out i can properly dent that in.
My shifter hole situation is gonna need some work so ill take out the console and work on sealing that up properly this time.
Couple of fitment shots

Auto trans tunnel cover plates,no problem:
Interior center console all wrapped up
Started bolting stuff on the engine, pops helped me get the AC and PS hooked up.
