92 F150 Custom, 180K, the indicator light for Rear ABS lit up the other day, now no rear brake lights, turns or four way lights, checked fuses, all good, checked fluid level for brakes;full, found RABSII diagnostic connection, got no codes when grounding the orange/black wire per the manual.....? Anybody got an idea what to look at next? Hand signals for now. Thanks

 

Multi function switch, it's the turn signal switch behind the steering wheel. It controls most of that.

 

Will look at this item, Thanx.
