Evo 4 with Evo 5 Ecu and Injectors

Since the Evo 4 ECU carnt be flashed I added the Evo 5 Ecu and Injectors. To get it to flash I added a pin I think it was to 79. My question is I have a loose wire hanging about now. Can it be added to the back of the obd port so it's just flashed like the Evo 5? If so is there a diagram of where the wire goes

Kind regards

I don't have experience with the Evo5 ECU, but if it is similar to the evo 8/9 setup, that wire doesn't go in the OBD2 connector but in a port next to it.

Might be worth posting over on like evo owners UK or somewhere that got the Evo 5 way back when. Maybe try a facebook group based in Europe?

Hopefully someone here will have some actual info for you but this is the best I have lol.
