Instrument Cluster Voltage Regulator
No problem on changing the caps.
Just make sure you use the heatsink and put in a place where air can flow around it and it does not get too hot (like under a black metal dash in the TX sun!). When the fuel tank is full and the engine temp sensor hot ( both sensor's resistance down at or near 10 ohms) then there will be a few watts being dissipated in the regulator. It'll get hot and burn up if not heatsunk. That is one advantage of the old voltage limiter: cooler operation.
