I have a 2010 CC SE with power mirrors without heat and would like to buy some big tow mirrors. I see that the OEM ones come with power and heat as well as another one coming with power/heat and memory. I would be interested in the one with just power and heat. My question would be that since my mirrors just have power with no heat would I need a different wiring harness to get this to work on my truck. Thanks in advance.
