When you have a Casper's field fix harness installed, isn't the whole point of it to bypass the factory dash and supply 12 volts to the back of the alternator from the wastegate solenoid harness? Theoretically can't you run and drive the car without any dash hooked up when you have the field fix installed?
Reason I ask is I'm trying to make this GNX dash work in my 86. The car runs 14 volts with NO field fix harness, stock alternator, stock dash. When I put the field fix harness on with NO other changes, the car still runs at 14 volts. When I take OUT the stock dash completely WITH the field fix harness installed, the car only runs at 11.8 volts. WHY is this? Once you take out the factory dash, I thought the whole reason behind the field fix was to allow for aftermarket dashes that don't hook up to the factory wiring???
