You need a set a anni seats to murder and some leather mk4 recaros.
They weren't Mk4 leather Recaros!
They were nearly new red/black cloth, heated, side airbag seats bought from MJ Interiors, that were trimmed by MJ in Anni cloth/leather.
He re-covered the front seats in new Anni cloth/leather, unstitched the Anni cloth on the rears, half covered the rear seats in leather and used the original cloth, fitted the rear headrests and modified the front runners to fit a Mk3.
The wiring is a mix of a Corrado VR6 heated seat loom (relays now live under the rear seat), a Mk3 heated seat switch and Mk4 seat elements, with the pins swapped to make it all work.
