ECU pin out schematics

A little info: For some brilliant reason the engineers decided to switch around some of the engine wiring between 1990 and the 1991-94 model years. This has caused a headache for many 1990 dsm owners since searching for some parts like coil pack, ecu, dash and power transistor HAVE to come from a 1990 car. Here's instructions on how to convert to 1991-94 wiring if you wish to do so. There is no performance reason to do this, it's only there to help if you need the info. It's not a cheap conversion unless you have a dead parts car in your driveway.
