Mirror heat wire?

[Kk4yvx]

Can someone tell me which is the wire for heat on this connector?
Mirror is pulled out of a 06 expy(model unkown).
I run the signal wire (green with white strip) already .
So that and the courtsey light is working, but I can't figure out which is the heat wire that I am planing to feed from my defrost button on the dashboard?
Thank you for any guidance.

The connector has 13 wires connected and 3 empty slots.

Does this match your connector? It's for a F150, but might be the same. If not, I'll have to look in my shop manual.

Thank you Skauber for the reply.
The connector pic you posted is the same as what I have but the wiring is different.
But it turned out that the heat is now working on my mirror.
The defrost connector on my dash was not pushed all the way in since I installed an aftermarket radio.
So now I have power, heat , signal and courtsey light. The only wiring I had to do was for the signal.
I will be doing the same for the driver side mirror as soon as I get it.
I'll post pics when both are done.
