Where to buy connectors for Ecu, IAT sensor`s and MAF sensor

Hello, I would like to know where I can acquire these connectors to make an adaptation harness to Ecu Gen 3 3sgte.

I have a st185.

If possible on the internet, ebay, amazon, etc.

I want to do this, the sensors already have them:






Thank you

They are made by Tyco. Should be the Junior Power Timer line if I remember right. Dig through the catalog and get your part numbers. Then you should be able to buy them from Mouser.com.

Last year I learned from someone on here that Toyota connectors start with "90980-". With the 5 digit number that follows, you can Google it and hopefully you'll find it from multiple sources. I don't know the numbers for any that you're looking for so I'm no help there. . . however, I did find this on ebay when I searched "st185 mass airflow connector". Looks like you can get it with a pigtail too. https://www.ebay.com/itm/For-Toyota...569937?hash=item1a5645e151:g:~MEAAOSwIIFbNvqP

When I was looking for replacements to my water outlet, I found them off ebay and https://www.bmotorsports.com/shop/

^That's only for the homologation models. If it's the correct one. Won't work for regular AFMs.
Most Toyota igniters share basically the same connector but the locating grooves are in different positions. Seeing as that's incorrectly listed as a regular connector, it's possible it's not the correct one for the homologation AFM either.
Just be careful before you order it.

SOME of the connectors have the part number on them.
You can order most or all connectors from Toyota too. Maybe more expensive.
The cars from the early 2000s up have the connector part numbers in the back of the wiring book.
SOME of the connectors are the same, EG the ECT sensor is the same at least up to roughly 2007.
For older cars [like ours] Toyota had a specific wiring manual that had all the connector part numbers.

Why not just buy the harness already made?

I'm using one in my st185 and it works great

Your celica is turbo 4x4 no sainz? Not watercooled?
What is the numbering of your ecu?

My celica is European (intercooler). Ecu 89661-20770 (same pinout as: 20751 and 17330 (but this is MR2 Gen 1, No gen 2 as indicated on the link)

Sorry for not answering the rest of the other users' answers yet

Thank you

I don't remember the ecu number right now but its just a regular gen3 Japan ecu.
Correct, its just a celica all-trac that had a air to air intercooler
