MD311121 Wiring Diagram

[Pasta_Ricer]

Hey everyone,

My friend has imported a 4G63 NT which possibly came from an RVR. The problem we're facing is that the wire harness has had its connectors cut on the ECU side. We just know that the ECU code is MD311121 and not much else. It also has an auto transmission code F4A23.

I was wondering if anyone had a wiring diagram for us in order to restore the harness or possibly adapt it to an aftermarket ECU?

Any help is greatly appreciated

For what car are you planning to use the N/A 4g63 engine? You don't need to use the RVR ECU if the car is 4g63 equipped car. Just use the harness, all sensors and the ECU that are already on the car.
I am not so sure what exactly your plan is but in case if you need to use the RVR ECU by rewiring, the N2- RVR ECU is similar to the early EVO (EVO 1/2/3), so look for the early ECU pinout in google, that should be useful.

We're trying to put it on a 1991 Galant.

Thank you for the tip
