I have search for one and couldn't find one so I made my own. This was made using data collected from the 89 TEWD, and it should work for 89-92 supra's. Now It's here to share.

I am about 95% sure that you listed the 89+ harness pinout with the 87-88 wire description table here, making it false info that can't be referenced properly for every single pin.

I am posting this to notify anyone who wants to use this pinout for anything.

Edit: I am now 100% sure of that. See this (http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=50) for the proper 89-92 table labeling each pin out.

Pre89 do not have grey plugs.

Here's the '89 TEWD he pulled the data from with diagrams of the plugs. If you flip though you may verify all the connections. The couple I glanced at appear just fine.

After you verify it remove your former post if 92nsx's pdf is correct.

I know the pre89's don't have gray plugs. The OP wrote that the PDF he has is a diagram for the 89+. The plugs shown ARE 89+ (gray plug) but the chart on the second page of the PDF describing each plug is the chart for the 87-88 ECU. Look at the No.10, No.20, and No.30. On 87-88, injectors 1 and 4 shared a pin out, but on 89-92, the pinout was 1 and 6. Compare his PDF with the link in my first post to the TSRM and you'll see.

You're not taking into account that his layout is looking INTO THE PLUGS, not the TCCS... it's mirrored from the chart you're looking at. ;) And I did just go over a number of the pins and verified them. His info is sound, please remove your post.

Yes the description (letting users know what symbol means what) chart is from a 87-88, but has nothing to do with what each symbol means. They are the same description. Order dose not matter for the description because that is all it is, a description of what the symbols mean.

No change is needed and PDF. is still correct.
