There are 2 types of auto trans for R31 Skylines.

The series 1+2 run an auto box that is mechanically/electrically controlled and the series 3 used a full electrically controlled auto.

The series 1+2 auto is identified by having a vacum hose that connects to the inlet manifold.

The wiring harness for the autos are completely different from series 1+2 to series 3, and are not interchangeable without a hell of a lot of wiring work.
