My original TPS before I started the swap was:
89452-30150
I've since tried:
89452-33010
Autozone : TPS406 which was a tps for 1992 SC300
Just saw on another forum the potential correct one I need is : 89452-30150. or Autozone: TPS4107 (which is the same for a 99 SC300)
So if I get a TPS from a VVTi 2jzge the code 41 will disappear and my car will see this thing lol?
Do I still need the reverse wiring or will that short it out?

Well that blows, the 1998/1999/2000 SC300 TPS VVTi part number EC3347 (Advanced Autoparts) TPS
IS 89452-30150
So this one WON'T work because it turns counter clockwise =(
I completely mis-read that posting... it meant for those just looking to replace tps not for those that upgraded their TB...

Ok... tried 89452-12050 from a LS400 (thinking it's trac tps) and I get the same results.
I get the same results with absolutely NO tps. It is set to idle great, worked that out with the cable.
Below is a link to a video of whats going on during WOT from 0mph
Also... the only plug that I mentioned before with nothing to it is my old Trac TPS side:
Does this get wired into the regular TPS too? Or like most have said, just left alone.
Incase you are wonder what the check engine light code is:
19 - Unknown
41 - TPS

Is there other things you need to do to bypass the Drive by wire, or have people been able to just change the throttle body, I am guessing you are on the stock ecu if so it may not be that easy, i think alot go standalone because of this problem.
also you may have to do something with the trac tps, are you getting any trac codes or even have a trac light?

By the looks, there is more to do to bypass the drive by wire. I think I'm going to leave this project alone until the AEM v2 gets installed and let them tune her out

yeah with a standalone there should be no issues with that throttle body, but I think its unlikely for you to get the stock ecu to cooperate with that throttle body, but the fun part will be controlling vvti with the standalone.
have you thought about retaining DBW and just going larger like the ls430 dbw throttle body is known to work and have better response than the stock ones at least on the IS.
