Need printed circuit boad schematic for Toyota 1985 truck 22re ECU Part number: 89661-35020
I could probably repair fried unit if I just had printed circuit boad schematic.
Hope someone can help!

Good luck. Your best bet will be a boneyard computer. I'm currently running a 1987 ecu in my 1985, so I know up to that year will work.

I've never seen one.

I also would check wrecking yards and ebay auctions. Look up a guy on ebay named toyotafoolish, he parts out toyotas and puts them on the net. I've seen lots of ECU that he parts out. Might get lucky...

Never happening. Proprietary Toyota information. Toyota ECUs are notorious for being real "black boxes". Tricky T on MUD has done some work and testing on 1FZ ECUs but didn't glean much information from them.

Look for a spare, they are generally no too expensive.
