Saw the post above on the 90’ D150.
A lot of project creep here but I used the gauge cluster out of a 90 D150 in my 83. That gave me a 100 mph speedo, oil pressure and voltmeter gauges and a VSS powered speedometer.
There are wiring changes but nothing crazy, I have a wiring drawing that I made if you are interested. I also swapped in the 90 fuel tank, gave me a 23 gallon tank, an in tank electric fuel pump and the fuel level meter then matched ohms with the instrument cluster. The fuel tank was a bolt in, I did add a support to the very front of it.
I am still running a carb in the D150 so had to add a fuel return line and a by pass regulator to cut the fuel pressure from 45 to 6 for the carb.
