HVAC controls heated mirrors pin layout
I hate when the factory does something stupid and tend to fix things with maintenance in mind.
Case in point the 01 K2500HD had a bad heater core and the radiator neck was cracked. So I went with a all aluminum radiator with aluminum sides that was a direct drop in replacement for the plastic tank side one, replaced the plastic Y fitting with a aluminum one, and tore out all the factory HV/AC replacing it with a summit heater. This is my tow pig/winter beater and function is the name of the game here. I started driving it last week and I still have a few small issues to deal with before the temp drops into the negatives. But, heat and cooling wise this girl is much better. One thing I did not think of when I removed the HVAC control panel(etc) and taped up the connections was that by doing so I would loose my heated mirrors. Now I could simply run a wire and a switch. But hey I already have the wiring, relays, and such sitting in the truck. All I really need to do is find what pin on one of the 2 connectors goes to the defrost switch(on the now missing panel) and then run a push button switch(with a light) to the other pin going to the relay and I will have heated mirrors that work just like factory. But after hours of searching I am having trouble finding just what pins to connect. Anyone know what pins to soldier into to complete this connection? Much simpler layout with a soon to be added button. https://i.ibb.co/7bZtzzY/20201005-213204.jpg |

I have the wiring diagrams for the 2005 model but 2001 is a lot different.

Here's a good overview from Eric O of what's out there for wiring diagrams and service info.
