Another Mopar Off My Bucket List - Barracuda Fastback

I DETEST DASH WIRING!! It's been really frustrating.

I started out with problems with the water temperature and fuel level gauges. Now the oil pressure gauge has stopped registering. There is a 5 prong connection on the dash's circuit board that sends the signals to the gauges. I have had it on and off several times. It will only attach one way so I know it's not backwards.

When I'd had the cluster out I'd cleaned the 5 pins and coated them with dielectric grease. None of the pins appeared damaged. All of the online research I've done seems to point me in the direction of the voltage regulator that's attached to the circuit board. The dash framework prevents access to it while the cluster is in the car.

I am still confused. On the one hand, I've read that when the regulator fails, - none of those 3 gauges will function but my oil pressure continued to work after the fuel and temp gauges stopped. NOW that all 3 are out it would seem to be the regulator. But before the oil pressure gauge stopped was it still because of a bad regulator? I've also read that a bad regulator will fry the gauges. I sure hope that's not the case.

I guess I'm about to pull the cluster out again. I'll rob parts from the Charger if I have to.
