I am attempting to change my manually folding mirrors to power folding mirrors. My existing mirrors are heated and have turn signals already implemented. I have already purchased the new switch and new power mirrors, just haven't arrived yet. Will I need to purchase a new wiring harness as well, or will I have to rewire to compensate for the power mirror option?

I suspect the wiring harness and connector from the door panel controls to the mirror are probably the same. The male connector for the new mirror probably has an electrical connection which mates up to the powered female connector already in the door. Wait until all parts arrive and compare the two mirrors at the electrical connection. If there is a wire on the new one which the old one does not have I suspect you need nothing else.

Thanks for your help. That was what I was going to do, just didn't know if you happened to know if the lariat already came prewired. I can't imagine them using a different wiring harness when it already has the heated mirrors and turn signals but I guess I'll find out soon enough! Surely it's just one more wire that operates the power fold option. Just trying to get all my parts lined up before I took my door apart and realized I still needed a wiring harness.
