Will the power mirror off of a 03-04 Chevy w/power fold,heat,turn signals wire up to a 99 GMC w/o any power options on the mirror? IF harness are required what harnesses do i need?

I put 2004 power mirrors with turn indicators in my 2000 Silverado. The wire harness will NOT work. I found an auto electric worker that wired it up for me. It is point to point wiring. I love having blinking mirrors. :guns:
