on the 2JZ -GTE auto ecu there are three plug ins.
E10 A and E9 B
E9 B is a double plug that has a bolt holding it onto the ecu. it's part of the engine harness. but i guess E10A is part of the body harness and i don't have it. it's a 40 pin connector. i can't upload a pic, says i exceeded the file size limit by 1.06 GB
