Series 2 Rb25 ECU on series 1 wiring harness?

[MeanS14]

Im not sure if im posting this in the right place but will a series 2 Rb25 ECU work on a series 1 motor and wiring harness? I fried my series 1 ECU and now i cant find any for sale, all i can find are series 2.

Has anyone tried this? Im still not finding a series 1 ecu for sale only series 2. I know the coilpacks and engine harness are different on series 2 compared to series 1 but ive been told it will work. Anyone have experience with this?
