Hey Dan, if you have the OEM wiring on your Ford then you should be able to tee off of the brake light circuit (if it is isolated) for the 3rd brake light and then tee off of the 12V power wire and use a switch like part # PK34513 to turn the dome cap light on and off separately from the other lights on your Dakota.
If you don't have the isolated brake light function, then you want the Pacer Performance 3rd Brake Light Logic Module # PP20-702 which isolates the brake signal apart from your turn signals. Simply run wire from this to your 3rd brake light and then tee off of the 12V wire for the dome light.
As far as keyless entry goes, we unfortunately do not have anything, but if there's anything else I can help with please feel free to drop a comment and let me know.

Hey Dan, how did your wiring project go with the logic module and toggle switch for your Leer topper lights? Your update could make it easier for others trying to wire their brake and dome lights the same way.
