You need the ECU/UCH/Looms/Decoder Ring/Key/Ignition Barrel from donor car to get it running on the standard management. Theres no way i'd say you'll be able to repair the loom if you've got no experience I wouldn't even tackle one and i've got a reasonable understanding of how it all works.
You should be able to get a loom from cliospares or SRB i'd have thought, unsure on cost though.
