Hello
I saw on this forum https://www.ford-trucks.com/forums/11...-backfeed.html

Here there was a problem with rear brake lights malfunctioning, At the moment i have a 1996 f250 7.3 with the e40d.
I have a back feeding through my braking system as well and my T/C is unlocking when cruising down the highway because the truck believes the brakes are being applied, as well the cruise control not working to due to the same reason. I have ruled out every, checked my grounds on bed, frame, cab, fenders, rad support,checked brake switch, Brake controller, Shiftlock Resistor and shiftlock actuator. except i have not checked the recalled ignition switch and my third brake light is burnt out but was burnt out before this problem started
In addition When i unplug my brake switch and my MFS the only brake light that is being back fed is the passenger side brake light, once MFS is plugged back in, the power is then fed through the MFS too the drivers side brake light. Also the pass side blinker does not flash it just stays lit solid, i changed hazard and blinker flashers in fuse panel. As well as the hazard lights will not flash. All these little problems only happen when the key is on, when the key is off the hazards work properly and when brake is applied with key off lights work properly, along with headlights and tail lights work properly.

This problem randomly started happening, i have all data the wiring on the truck and traced out the other odd problems with the tranny and my pass side blinker light and hazard lights not working proper to the back feeding on the brake light

Can you guys possibly help me?
