From non cup to cup wiring

[The Beardo]

Because I've done away with the air con and in the process of doing away with the abs system, I'm wanting to fit a cup loom to the Clio. My question is, apart from fitting both engine bay loom and interior loom, do I need anything else such as uch module, ecu etc

Regards

ecu can stay, uch can stay but needs re configuring or you'll have service showing on the dash. not sure if you can sort the abs light out through the uch or you need cup dash?
