There are at least five threads in this section from the past two years where someone asked for a wiring diagram and got either no reply or a broken link. This forum has them, it's just not organized anywhere.
Starting a permanent index. I'll add to this as I find more, and please post anything you have.
What's confirmed available on this forum or commonly shared:
1UZ-FE non-VVTi (1990-1997) ECU pinout
Crown UZS131 full translated wiring diagram -- one of the best resources on the whole forum
1995 LS400 wiring diagrams -- partially covered in the "wiring Diagrams 1995 1UZ-FE" thread, incomplete but useful starting point.
OBDII and data link connector pinouts -- the "Some OBDII and Data Link questions" thread in this section has solid verified info across 18 replies.
What's still missing and would be most useful:
VVTi 1UZ (1998+) full harness diagram
3UZ-FE complete pinout
2UZ-FE swap harness documentation
If you have any of these or know where they live, post them here.
