2020 Tundra TSS - Issue with Trail Ridge Mirror Install

This is my first post so please redirect me if I'm posting this to the wrong forum.

I have a 2020 Tundra TSS, I purchase and installed a set of trail ridge mirrors with BSM, heater/defrost, turn signal, power adjustment, manual fold. Only to realize after I installed them that I don't have BSM.

Everything works flawless except the heat function.

I'm assuming I need to move wires at the connector, but I can't decipher which wires need to be moved and 1a auto and trail ridge don't seem to have any wiring diagrams. Can anyone help me out with the following:

- Does anyone have a wiring diagram for these trail ridge mirrors
- Can someone point me to the wires that power the heat on the tundra at the connector?

I searched the forum but haven't found anything specifically relevant to this, any help or directions would be much appreciated!

This might help for the truck part, not so much the trial ridge mirror.
