I’m damn near done with my manual swap. The question I have is do I have to reset the ECU if I’m using the same wiring harness’ it came with? So when I plug everything back will it just turn on and start?

ECU/ECM came out the same car as the wiring harness 2013’ and the trans same year 2013’ but different car. Would I need to reset? And if so do I have to tune it? Or does the reset make it so the transmission and ECU are synced together. If not do I use my OFT and tune and if so what tune and link for said tune?

Thank you!
