So, you purchased the Ford integrated brake controller from a 3rd party and installed it in your truck that didn't have the ITBC from the factory? ("OEM aftermarket" is a confusing mash-up.)
There were some early problems with the integrated brake controller when the current generation of F150s came out, but I haven't heard of a controller failure in a while. Do you have any idea when the one you bought was manufactured?
