I have a 2002 Silverado. After breaking my mirror ,just the glass, I
discovered I have a couple of extra electrical connections inside the
housing besides the remote control wiring. I am guessing these are for
turn signal and mirror defrost. What would I need to add to make this
work? The new replacement mirror is two way with everything but an
arrow masked off from the back side. I was thinking about putting a 5
watt 47 ohm resistor in for a heating element and an LED brake light
for the turn signal unless I can find out what are the factory parts.

Where would the defrost switch be located.

The factory heated glass is a metalized film item, very low resistance

control module and you have the proper switch.
Same with the turn signals.
