For wiring diagrams go to the local public library. They have an automotive section stocked with Mitchell Manuals, like shops use. Make copies for a couple bucks.
I mounted my ECU behind the lower right, passenger, kick panel where the factory 22RE ECU went. Had to hammer some clearance and it's a tight fit but it works. I used a Howell harness.
Get a goo pin extractor to remove the Toyota wires from the factory connectors. Do it right the first time. Electrical hack jobs are the worst kind of everlasting nightmares.
I'm in Hanford if you need to see how I did mine let me know.
