Standalone for AE86 4age to AE82 4age

[Chrisso]

Have a look at the plugs of the AE82 ECU, it should be the same 10-18-14 configuration. The only possible difference will be in the pin functions. By that I mean that pin 1-10 in your AE86 ECU might have a different function to pin 1-10 in the AE82 ECU. Appart from finding the wiring diagrams for each one, you can take the covers off and have a look at the circuit boards. There should be a designation for each pin. If these all match, then plug and play. If not, then find your wiring diagrams and determine what each pin does.
