I agree with you, I think three is too short. If we could find out exactly how the truck senses a trailer hooked up to it it probably wouldn't be difficult. I know it involves the electrical plug for the 7-pin connector, but beyond that I'm not sure.

I think it goes through the electric brake controller, I have hooked up one without electric brakes and the truck has no idea it's back there. I too would like five to be standard, but not sure how. Probably a mouse click when a computer's hooked up is all it would take!

I actually can't get the five blink working with my new trailer.
It has tandem brakes...
Maybe it never worked and I thought it did.

My 5er and 10K tandem both with RV7 and trailer brakes will not trigger the 5 blink. I was hoping the last reflash would add that feature. Nope.

Mine is a July '10 build, but you'd think that would not matter. The MCU knows when you have a trailer connected and the 3 blink is triggered by a momentary switch closure, so it would seem to be a minor code change.

You would think not but I brought it up only because a few of the early builds don't have some of the software "features" the later builds have.
I think one was the automatic seat adjustment based on a key but I'm unsure if that's it.
You would think that would be a code change but others have posted here Ford won't offer it in a standard update.
Or maybe this isn't a XL or XLT feature...
