Heated Rear Window retrofit

[First time transporter]

Hi. I have a t6 DROPSIDE single cab with a heated rear window fitted. These vans were only fitted with a plain rear window so I guess that was smashed and the only one they could find was one with a heater. I have a dash switch I’ve purchased for a t6 rear heater, but can anyone tell me what I’m going to need to make this work as it’s not plumbed in at all, the wiring in the window tests fine (continuity test), I’m guessing I need some wiring, relay and the plug for the switch? No doubt followed by coding ? Any information would be really helpful. THANKYOU.
