1958 adding defrosters on mirrors

Sadly there’s no prewired connectors in the mirror assembly housing. I’ve checked behind the mirror glass. I still need to take a door panel off and see if there’s wires there at the connector.

Pics of the side mirror with glass removed. Those clips holding the mirror glass are stout. Tricky to remove. Used a 90 degree pick tool to reach behind and release the tabs rather than pry on it.

I’m also curious if there is some way to make this work. The heated glass assemblies themselves are quite cheap. Not sure how useful they’d actually be, since my car lives in the garage overnight. We’ll see this winter.

Funnily enough, the base model in Australia, of all places, comes with heated mirrors. 🤦‍♂️
 
I added heated glass to my Taco, it was just a matter of adding two wires to the OEM connector as it was pre-wired from the connector to the switch.

That would be ideal. Was the connector in the door or under the dash somewhere?

I think, been awhile, it was the connector behind the dvr's side kick panel. I had to run new wires from the glass, through the mirror, door and door frame.
 
Will be watching this space, as this is the only "option" I would have liked to have. Odd that there is a heated steering wheel, seats, and the defrost options, yet no heated mirrors. Got to love Toyota thought process at times, or lack thereof. It is all good though, totally enjoy my 1958 model, it was the right one for me.
 
Here is what I have on the wiring.....

Thank you for the uploads . I was going to do the rip and pray method.

I would trade the heated steering wheel for this option. That sucker get hot!
 
Someone was asking about this on Youtube. I know in the past I have wired them to the rear defroster wires on other vehicles. Probably a connector in the footwell area with wires that run down the passenger or driver side (under the side sills).
