I have remote start and I think mine are disconnected as well.
If you have a mopar remote start, it would not work if the hood switch was not connected.
Mopar remote start uses a hood latch switch that is integrated into the hood latch assembly. If you have a mopar remote start the connection is on the left side of the hood latch (when viewed from front of truck) and would be clearly visible in the photo that motorider provided. I have seen some trucks have the plug and wire there for the hood latch ready for adding remote start after it leaves the factory, but somewhere along the build it does not connect to the BCM. In this case, when adding a remote start, another wire and plug has to be routed from the hood latch switch to the BCM. I guess what I'm getting at is if you have a mopar remote start and you see this same connector unpopulated, that may be the reason. And by looking at motoriders photo, the truck does not have a mopar remote start, because the hood latch shown has no switch.
