Look at the Wiring Harness Repair Manual; it's in the Resources section and covers all 80 series (and more, besides). The terminals are type 2.3II; you can get them from
Ballenger motorsports in the US (the page is only an example, but they are the correct terminals); I assume they're available in the antipodes. Get the rear seal (plug) and a crimper, too.
The manual has instructions on how to properly disassemble the connector housings (that is, how to "depin" them).
A "repair wire" is available from Toyota; the part number for the various wire sizes is in the repair manual (there are also barrel connectors listed there, but you can get them at any parts store). It's a 160-mm or 500-mm long wire crimped onto a terminal; I would not recommend them, though. They were designed for service technicians at dealerships, who had to make wiring repairs. You still need to connect one end of the "repair wire" to the harness, so it's of no real benefit, IMHO. All you need is a new terminal. Cut the wire at the base of the terminal and crimp on a new one.
The 1996 US spec 80 series was only built with the A343F transmission, so you'll need to use a 1993 or 1994 EWD. Those were the only US models fitted with a A442F transmission.
Unfortunately, the wiring harness for the transmission isn't listed separately in the EWD, but the connector you want is "E2", on page 22 of the 1994 EWD. If you look on the back (wire) side of the connector housing, you will see a five digit number embossed there. Search the repair manual for that number. I think it's 11663, but you need to verify that. Those five numbers are the second half of the connector housing part number; the first part is "90980-" (same for all the housings on the 80).
Once you find the last 5 of the part number, CTRL+F the pdf for that number. You'll find the housing picture first, and then a table listing the specs for it. It'll look like this:
In this example, the housing 90980-11663 is a female housing, having (6) type 2.3II terminals and they are sealed. Here are the specs on the type 2.3II terminal:
The "sleeve" listed above is the tube type crimp connector I referenced above.
Part numbers are listed, but Toyota doesn't sell them anymore. They are sourced from Sumitomo, as are the seals, wire and connector housings.
Ballenger in the US sells mainly for the motorcycle market, but has various Japanese autos listed as well. If you don't want to try to source from here, try a Japanese motorcycle electrical supply house in your area. They will have these parts.
