So attached is a picture of my switch it’s mounted on a metal brack alongside with 3 aux switches one controls LP two are not in use .. for some reason my switch works when’s it wants to ... it slwsus has power and is lit up but sometimes I go down from 5 to 4 and you won’t hear The engine rumble from a hiss tune or vice versa.. I was told it’s grounded in the cab can’t find it .. I am scared to open ECM as this is my first diesel .. One buddy that works at a diesel shop said start by switching out my switch to a knob like dsp5 .. I like my digital lol .. feels like once I drive it for a little bit a couple bumps on the road then all of a sudden she will shift on The fly .. then randomly stop .. and she will not shift on the fly in park
