I’ve installed the Factory Tow Controller. Looked around everyone say to put relay in spot #9. Fuse in spot #21. Already have a blue fuse in spot #21 This is the fuse box under hood

thanks

 

Is there a question missing from your post or.....?

 

Where do the Relay and Fuse go??

 

Under hood fuse box

The point is that these trucks came from the factory with those 2 items in a bag instead of installed, so there are comments to install them if needed. But, it has been a decade, so who knows what someone has done to your truck. Install them and move on.

 

True. At dealership for programming

Thank You
