i finally dropped the 3sgte into 90 celica but the 3rd ecu plug from by body dosnt fit. i know it needs to be re wired but i cant find the pinout's for the 5sfe any where. i think i found the 3sgte pinouts at this website http://www.alltrac.net/reference/ST185ECU.JPG but i still cant find the 5sfe. any suggestions on what to do, or any links i can be sent to?

I did a 3SGTE to 3SGTE swap so I dont know anything about the 5FSE but maybe this will help you with the 3SGTE side of things. Keep looking, Im sure you will eventually find what you need. My swap took me 5 months. I seem to be the exception though.

This is the best diag there is IMO. It wont load for me right now, dont know what the deal is. I have it saved if you cant get to it I could email it to you.

Do you have GTS? If so then you do have the 3rd plug and it would plug into the JDM ECU.

these are pinouts for the body plugs. the ones next to the ecu.

dude, u are the man haha. i think i got this wire thing down now. thanks for all the help, if u read through the previous post u will see that u helped me with about 80% of my swap lol. i just dont have that 3rd ecu plug. when i bought this engine from jdm it didnt come with it so i gotta go back to the jdm in philly and get it. also they took the flywheel and the bolts that go to it. so i tried to put the bolts from my 5sfe engine but found out that they dont fit but im pretty sure u guys already knew that haha. any way if any one has a stronger tranny for this engine please let me know. currently im using my 5sfe tranny fwd. any way hookecho, thanks a million. i'll post picks as soon as i get it running. hopefully soon.

The "best" tranny that people use is the MR2 Turbo one with LSD. A close second is the non-LSD MR2 trans.

For ECU pinouts, just make sure you know which version you are using. There are 2 different configurations for the 3SGTE pinouts (90-91 and 92-93). Here is my favourite 3sgte pinout diagram because they are all there:
