Heated screen and heated mirrors usually iirc

Usually you have them available on the dash loom, however, depending on the spec of the other looms you'll have to do a bit of work to get them all plumbed in.
Easy test is to check relays r22 and r26(heated screen) in the front fusebox behind the glove compartment.
They may not have the relays in but look through the holes for the 4 spade terminals at each relay position.
No terminals means aw hell
