Thanks MarkMc for the very fast reply!
For the record, should anyone search this, I have just been sent pictures of 1ZZ-GE coils which appear to have the exact same connector style, and the following info. I am ordering some tomorrow, I'll confirm they fit later in the week, hopefully

Use at your own risk!
Here are the Toyota part numbers for the 1ZZ-FE coil pack connectors:
! x Connector: 90980-11885
Pins (x4): 82998-12440
Toyota connector pins with 160mm wire - Toyota P/N 82998-12340 (USD $4.43 each)
I have not used these, so I do not know how many are required - likely 4 per.
Pinout, looking into the coil connector moulding itself :
Left to right : Ground - Trigger - Tach - 12V
