I have a 1991 rx7 with a swapped s4 engine. I have a wiring harness for the S4 and the only problem is I'm having trouble finding a pin out for the 1987 ECU. I don't want to replace the body harness that goes into the ECU. My plan is to just solder the wires. Does anyone have a diagram for the 1987 ECU? I looked at wiring diagrams and found nothing for an ecu pin out.

Thanks

 

You can pull up the Adaptronic PnP PDF off their website, it has a pin out.

 

Thank you very much i have been searching forever!
