Hwy guys ever since i but my flat bed on my 93 f250 7.3 ( bout a week now) my abs light comes on every now n then n stays on for bout a min. or two then goes off. Anyone no was this means

 

Maybe you pinched a wire or something? As far as I know the abs... or rabs... is in the rear axle, unless it's different in your model. Only thing I can imagine is that you snagged a wire somewhere and its grounding out maybe and causing the light to come on...

P.S.. I like the picture you got there.
