Hello all ,working on my dash ,it’s out of the car ,came across a voltage regulator it’s on the back side of cluster near high beam indicator,I don’t see what wires go to it one terminal has a condenser looking thing mounted,I do have a short black wire from harness that would reach on of the other terminals ,but the one to the right I have no clue ?Any ideas it’s easy now just trying to sort out wiring before I install dash thanks
