I just swapped a 90-91' diesel dash with the electronic speedo. My 6 speed Eaton Fuller has a VSS on the output shaft so I figured I could get a signal from that. I hooked one of the one sensor wires to the gauge signal and the other to ground. Nothing on the gauge. If I tap the ground wire on the bare metal floor pan it makes the needle move... What type of signal does the dash gauge need a ground reference of a 12v reference?
Once I get it working is there any way to adjust it for tire size and gear ratio?
Any help would be appreciated!
