Can anyone tell me where the ECU for a 1992 SC400 is located?

 

under the passenger seat

 

---well the sc400's is actually under the dash on the passenger side under the rug.

Where the passengers feet would be.

im not sure but i think the sc300's ecu is actually under the seat as ive heard a few members talk about it.

 

Its not under the passenger seat, its under the floor mat area on the right side of the car. Remove the floor mat, bottom kick plate, the glove box, and Wolla!

 

Thank you very much.
