I know this has been a topic many time before but could not find my problem. So my truck is 1994 F 250 4x4 IDI factory Turbo 7.3 with auto Transmission. I have recently rebuilt POSM and replaced VSS sensor.The problem is when I start truck all is good , as soon as I touch the brake the speedo jumps around.It does not jump at all when moving only when stopped and foot on the brake.I was wondering if my trailer plug or trailer brake controller could have anything to do with this?
