This page is asking for help to find an ECU / harness pinout - related to MembersPage/MarcellGal/EngineSwap/TaskList

We now have the Daewoo harness matching the engine side and it looks better to use the Daewoo harness, cutting off the ECU side connector (instead of using the original car harness, and making adapter cable).

We now have a wonderful program that has info about hundreds of engines.

This will make the GenBoard/VerThree install project for the Daewoo engine a gravy train with the Daewoo harness.

Feel free to update this page with your comments.

[some unresized raw pictures] about the harness.

We know the TPS connector pinout, so that gives some hint to verify the pinout - well, it doesn't match, even if I assume there was a mirroring error that resulted in swap of GND and +5V - the TPS signal itself does not match the book (see below).

Looking at the 3 pin triangle shaped connector of the harness (note: NOT of the TPS sensor Jason, did you read this note?), tab (lock) at "6 oclock" the GM standard signals are:

(Jason, it is likely that you swapped +5V and GND here)
  • I appologize! I just now thought of it after seeing this message. There are 2 GM triangle type TPS's. I have the backwards rotating one so it's on the back side of my TB and out of the way in my engine bay. I never even considered that (been 2 years since I put it on there). If you had a 1995 Chevy pickup with a 4.3 liter v6 it would have been right. ;-)

I also verified the control pins for the InTake/VariableIntake solenoid, draws 285mA from 12V (polarity shouldn't matter, right?). This matches.
