Ok so this may be long but I need some help
2001 36 FDDS 8.3 Cummins ISC motor
The dash gauges are out ( speedo ,tach misc ) the idiot lights ( sorry) are not and they function correctly
not all the gauges are out , the engine temp gauge buzzes and actually works which is telling me I'm getting signal from the ( black box) in the engine bay.
The gauge needles Tach and speedo are pegged and are not working or buzzing which tends to make me believe its the actual gauge and not a signal source . ( black box)
Does this sound correct and if the black box is to blame , where on earth can you get this thing ?
remodeling the entire couch and I would like things working correctly yes Im aware of the after market apps and tablets that can run engine specs but I just want things to work and not bypassed , OCD that kicks in
