Bmw F32 3.18i ls2 ecumaster black swap

Hello everyone, I swapped an LS2 engine to my BMW F32 3.18 manual vehicle.I connected ecumaster black.
I don’t know how to operate parts such as the start button, my indicator, my air conditioner, my DTC button and traction control.
There is no garage around me where I can get professional help and I have to do my work myself.
Can you recommend someone or a booklet that can help me with this?
