looking for full electrical schematic 1996 240sx MT

[blindside73]

I've been searching for a few days but can't find a full electrical drawing/schematic (similar to the foldout for the S13) for a 1996 manual 240sx.

I'm trying to make my own engine harness that connects to the stock trans harness and to my megasquirt ms3x (Full sequential and ignition)

Thanks for the link, that was the first place I checked which didn't have all the pinout definitions for the following connectors.

The FSM sucks when it comes to the engine harness schematic.

The actual wiring diagram for the engine is not in the Electrical System (EL) document.
It is spread out to different sections in the Engine Control System (EC) document under the diagnostic section for each component. So to figure out a connector's pinout, you have to do a lot of searching and compile the information yourself.
