Evo 8 front ecu question

Hi guys have anyone here ever gotten rid of the front ecu? Or mounted some where else making your own panel? I made a harness for my evo and relocated the complete box inside the dash but now I want something more professional. If anyone here could shed some light I would appreciate it.

You're probably best considering a PDM to control the headlights etc that this little box is normally in charge of.

That’s what I was thinking. But I’m a bit scared lol to do a pdm would I be able to retain everything I even still have ac in the car lol
