just to add my findings. I didn't take apart the dash looking for a controller end, but I did wire up a spare tire swing out lincese plate led and used etc 4 way as a running light power. I was curious as if the 4 or 7 way was wired up and had fuses installed form the factory, they do. Some cars its an add on if your doing towing.

just a note, toyota has changed course on how they wire vehicles now. it use to be they would have wire looms pre-made with everything and just not the connecting switch or what not.

now a days, toyota has specific wire looms for those trims that either have a feature or not. so they are no longer leaving pre-wired connectors for the end user to piggy back off anymore.

its been noted on the new tundra's even as simple as the higher end side mirrors vs the lower end mirrors not having the connectors for the features the higher end mirrors have to plug and play swap out of the lower mirrors
