Rearview Mirror

I have an 04 Silverado 1500, I have a rearview mirror with electric to it for the passenger airbag sign on or off display. I want to know if i can replace it with a mirror from an 04 tahoe that has auto dimming, temp and compass. If so, Will i need to update the wiring harness? I dont know how many wires are currently going to the mirror.
