07 grand caravan side view mirror question
 

My recently purchased the GC SXT mentioned above came without heated mirrors, however they are powered. I was wondering what it will take to get heated mirrors?

Is it as simple as finding heated power mirrors and plug and play? Or is it more involved?
What years are compatible, I am only finding 04,05 heated mirrors on E-bay, They look right but do not know for sure.

Thanks for your help.
