turn signal wiring

A couple of years ago I installed tow mirrors on my 99 Yukon.
I am replacing the carpet, and have the front seats out.
I want to connect my turn signal mirrors while access is easy.
Please look at the attached picture ...Are these the light and dark blue wires that I should tap into????
Kinda need to know sooooon
Thanks Ron
