Toyota has a manual called Wiring Harness Repair, RM1022E, available on-line, wherein they pretty much tell you that if you want to repair a broken wire or terminal at a connector, they want you to buy FROM THEM a precrimped terminal/wire and then splice the wire into your wiring harness. I do not want to have splices (butt connectors) in my wiring harness, and I certainly do not want to pay Toyota prices.

Moreover, being a DIY guy, I want to be able to terminate wires myself.

I have been working on different parts of my 1994 Celica for the past decade, and am just finishing up a total rebuild of the engine, and need to fix a few wiring problems, but I cannot find a source of wiring crimp terminals or crimp tool that fit the Toyota connectors found on my wiring harness.

I have been going around in circles for days now, trying to find a place to grab hold on this knotted ball of string (vacuum of knowledge), and am hoping that someone on this website can step up and give me a definitive answer that leads me back into the sunlight. Surely someone has been in this same situation, right. But try to search for it on this website. . .

There's Ballenger Motorsports and Corsa Technica.

I used them both for connectors and terminals. The crimp tool you would need is the Tool-CF3 for most Toyota terminals, both sealed and unsealed, but the Tool-CF4 would be ideal for any sealed ones.

Dug through my notes, found this (from mr2oc.com):
https://www.mr2oc.com/threads/toyota-ecu-pl...rnesses.167561/

This is for ECU connectors, but they're same for most of the car, so should apply.
they're amp/tyco
small terminals for male plugs are part # 316836/7
large terminals are part # 316838

To mkernz22 and slavie:

Thank you both for taking time to address my question. I sincerely appreciate.

Some of the information points to links or part numbers that no longer exist, however you do point out resources that may end up being helpful. I have not yet perused the Amp/Tyco part numbers and expect they will be productive, once I get into the details.

I did make a contact that led me to a high performance organization located in Melbourne, Australia, EFI Hardware.

They had discovered, they say, two of the most common toyota terminals that are used in my 1994 Toyota Celica ST, and they sell a terminal kit that includes those terminals along with the weather seals for under hood connectors. They also
sell a crimp tool for these terminals. They did not disclose their terminal supplier.

Am providing a clip from my conversation with them in case anyone might find it helpful. If you are into speed, power, racing, your chances of learning exact Toyota connector pin terminal part numbers go up dramatically because more people want to supply you with help; for profit. My initial hope was to find references to terminals for like ANY Toyota vehicle.

Not sure if you had trouble finding the exact TE pin I included the number of: TE 316836, and TE 316838.
DigiKey stocks the smaller 316836:
https://www.digikey.com/product-detail/en/t...48TR-ND/2331081

~$0.10 USD each. Though looks like it's 6000 minimum. Any retailers selling in smaller quantities will have higher price, naturally. Either way, my point is, these are readily available.
Link to TE site, has exact specifications so you can measure against any pin you have on hand if you're not 100% sure:
https://www.te.com/usa-en/product-316836-1.html

The crimper EFI site offers looks like the standard chinese crimper (knockoff of Delphi 12085271) - same thing as Tool-CF3 from Corsa and many others.

Finally, if you're gonna be working with connectors, get yourself a quality de-pin tool. The cheap chinese ones are crap. I once bought an original Toyota replica for $15, which I thought was expensive, but I've de-pinned more pins with that tool than any other I have. Totally worth every penny.

Hope this helps.

Very helpful, Slavie. Thanks.

Do you happen to remember the source of your $15 de-pinning tool? I have been using my smallest jeweler’s screwdriver, and know it isn’t the best tool for the job. I CAN make it work; just keep at it till the pin pulls free. But surely must be damaging some of the snap lock mechanisms.

I've tried to find that de-pin tool for other forums posts in the past - no luck. I purchased it on eBay way back when. It's stamped JCC 10 (1.0mm I presume). It's sturdy shank cut at a 60 degree or so angle.
I posted it in my mini-guide on depinning on TN.com (last pic in that post):

Also, just stumbled across this treasure trove:
