E36 convertible hardtop question.
I am going to purchase a Hardtop for my 99 E36 M3 convertible.
The top is off of the same year M3 convertible. I asked him if he had the kit for the hardtop that makes the lights and defroster work, and he had no idea what I was talking about. I was under the impression that in order for the lights and rear defroster to work you need a kit. He said that all he does is lock the top and everything works. He also said that it was the same for another E36 convertible he had and an E30. Is this true, and if it is not where on the car is the kit/harness/adapter located so I can remove it. Thanks.
