Are all Auto ECUs the same from 91-94 URGENT NEED HELP

[Matrixhunter]

Hey just need to know do they have the 3 connectors and are they interchangeable. Would a wiring harness from 1994 talon tsi have the same connectors to plug into a 92 talons TSI

I put in a 94 tranny in a 92 so i need to change the wiring harness to 2 connector style for the 94 tranny tcu. 92 one doesnt want to operate it. Thanks

All ECU's will interchange between 91-94 for Talon, Eclipse and Laser. Just make sure the ECU you replace is for a Turbo Auto. You can use a Turbo 5speed ECU but it will run the car a little rich. Sorry to hear about the TCU units having different plugs from year to year, but that is definitely not the case for the ECU's.
