Updating this thread too. My heated side mirrors are installed and working in my EX 6MT. The only component not yet completed is tying the activation of the mirrors via the defrost switch for the rear window. The switch itself is routed to the ICM (internal computer module) and adding any extra load (even a small relay coil) is too risky to chance burning something out that's way more expensive. The rear defroster relay is located on the passenger side engine compartment. I need to run my mirror relay coil hot lead to the signal hot lead of the rear defrost relay to both activate simultaneously. That way the ICM controls the timing of the circuits and all is well.


Cheers

 

please check out my other thread for the final update of this project the heated side mirrors are fully functional and operating off of the defroster switch. I have pictures and video on the progress and result
