Turn Signal Mirrors

So I was at a KDMax tuning meet on Sunday. My friend was with me. He has a '16 SR5 Premium, and it has turn signal mirrors.
My '17 SR5 doesn't have them. So I was wondering if anyone can tell me if it's already prewired for turn signal mirrors? Because if it is, I want to add them to mine.

 

@Old Red makes or used to make a full harness.

 

I don't think it is???
but Old Red made some harnesses to add them to a TRD pro. might be the same?

As stated, your truck is not really wired for the turn signal mirrors; you could says it's partially wired. The best way to add the factory turn signal mirrors is with Old Red's harness; this is as close to factory as you can get. You will need to buy mirrors with turn signals installed and Red's harness. While you are at it, replace the inadequate halogen puddle lights with LED bulbs. It's a great upgrade but an expensive one. Expect to spend over $600 on this.
