Can someone post the ecu pin out for a USDM 93 All-trac - 6G Celicas Forums

Trying to compare to 93 mr2, but obviously it isn't the same. A couple wires different. Just need an exact reference. I'm doing another Honda chrome ecu conversion on a celica.

Thanks Manny, but the problem is I have seen those pinouts numerous amounts of time. And thats for the JDM 93 gt-fours. I need a USDM st185 pin out. The pins are a little different.

I've seen that one before too. I don't think thats a 93 pinout though. On plug B, the G- wire is missing for the Distributor. Its gotta be something else. Too bad the links on celicatech are busted. I swear its very similar to the 93 MR2 pinout but a couple wires don't match and don't know what they go to.

Actually quite a bit don't match up. I'm just going over everything with an ohm meter, but still can't confirm which color wires mean what. This is the GAYEST thing ever. wished I had a 90-91 harness to deal with.
