I've read tons of posts and threads mentioning the break controller but none that says how they operate, proportional or time delay? I ordered my truck with the max tow so the controller is included. I'm hoping it is proportional. I had a time delay in a past venue and use a nice Tekonsha in my present rig. Much better control and ease of operation. Anyone know for sure? I also did a search if I could come up with something from Ford with no result.

 

It is a proportional controller.
