Is it possible to pull an automatic headlamp switch and sun load sensor from a 2005+ Dodge Dakota and install it into my 2007 Dodge Ram 3500? I know the switch is an exact fit and the wire pin out is the same but I don’t know if the sun load sensor can be used in conjunction to make the system a working automatic headlight system. I am wondering and hoping that it may be an easy upgrade like adding fog lights with the preexisting wiring.
I know that there is always the option of installing the 545T Nite-Lite aftermarket automatic headlight system, but I would rather use the factory switch with the “A” setting.
This is my current switch:
The 2005-2011 Dodge Dakota has this switch as an option:
I know that a lot of people don’t care about automatic headlamps but I would like to have them. Has anyone else done this or know if it will work or not?

According to what manuals I have access to, no. Both run on different computer systems. And how the auto headlights work isn't as simple as you think.
i could be wrong as I have limited written information for the Dakotas.
Also interested, not sure if this is something you'd be interested in either but my 06 seems to have the driving light feature not quite the same but...

I could be wrong on this completely as I only have limited literature on the Dakotas. But they seem to have different operating systems. And the light sensor is very complicated (it's basically a switch). And unlike the old days switches got complicated
Basically the light sensor tells the CTM that it is dark out. The CTM waits for that trigger and the trigger of the headlight switch being on automatic. Then it turns on the headlights. You both might be able to use the light section sensor and wow it directly to the headlight switch, but there is a chance it won't work.
wondering if one could wire a daylight sensor of some sort to a relay then doubles back to the headlight switch triggering the lights or even go to the level using the "auto" switch to control said light sensor/relay setup but im not up on how complicated everything has been made is a headlight switch a switch at all anymore or just **** attached to a computer board? Would the CTM noticed the correct switch has not been installed

The CTM doesn't what switch is installed so to speak. You could use the Auto headlight wires and wire up something and it should work. You will basically have it as a switch instead of the complicated system Dodge used. Message member SHO Rod (he hangs out in the 4th Gen Ram section) and he could figure out how to wire it. He's a wiz as wiring.
