I have 1996 truck with power mirrors and no heat option. I bought a used set of power/heated mirrors that came off of 98-02 truck they are a direct bolt on , but how do I hook up the power and heat. I dont think the wiring or plug ins are the same, and is this even possible. I want the heated option,and I like these better than my cheesy chrome ones. Any help would would be greatly appreciated THANKS
