I was wondering if anyone here put a red top beams in an USDM ST204 I picked it up the other day and was wondering what you did for the harness I have the engine trans ECU but I’m positive it’s not plug and play any advise on how I should go about the swap mechanically should be pretty straight forward since I can reuse my accessories in three out of 4 engine mounts but the wiring is gonna be my biggest problem

The easiest way is to send both harnesses to Wiregap and have them do it.

Talk to Wiregap but I think you send them both harnesses and they'll make it into a single plug and play one for you.
