Cut and paste from mvpmotorsports

Greddy Throttle Position Sensor Adapter for Use with Greddy Intake Manifold for 1993-98 Supra TT
Part # Gr 13910400
This adapter allows you to bolt on the Toyota OEM Throttle Position Sensor (TPS) to your Greddy Intake Manifold. This piece is not necessary if you have a stand-alone ECU as then you can use a different TPS. However, if you have the Toyota OEM ECU then you must use the OEM TPS and then you do need this adapter.
MSRP $58.00
Your Price $52.00

Anyone have a solution to this? I just bought an infinity q45 TB and was wondering how am I going to get the TPS to work? Was going to buy an adapter but I cant seem to find one for the SC.

greddy tps for 2jz is what you need , and you must use the ge tps as the gte tps turns in reverse of q45 throttle plate .. i use one on my intake for last 2 yrs , no issues .. just get longer small allen head bolts to secure it to side of tb , the ones greddy provides are short and a joke

Ok first what ECU are you running? If you are on Standalone you don't need an Adapter You can use the Q45 stock tps it works great with the 2jzs on EMS.
Pm me your cell number then ill text you the pics !

ok so it is understood that the GReddy adapter works.

i have the wiring for if it was going on mkIII supra but that was easy to google, also I have the wiring diagrams for both and have the q45 wired up and it is giving me signal output. One question though, there is a 5v and 12v power on the toyota tps, which one to use for the nissan tps? since it only has one power going to it?
