hope someone finds it useful

in case you cant access it for some reason...sorry the pics wont post

SR20DET Wiring Diagram




This is a copy of the Repair manual for the SR20DET S-13, Thanks to a Friend "Jack" of mine that lives in Japan.
Its in Japanese but can still be deciphered .


If you need a clearer picture of the Diagram E-Mail me. This is good to have for trouble shooting.
