I'm having trouble wiring the city lights in my ellipsoids to work. I tried tapping the grey wire in the ellipsoids with one of the grey wires in the parking lights, but it seems I did it incorrectly because I shorted out the parking light. I'm almost sure the brown wire is the live wire in the ellipsoids. I'm just not sure what the grey wire of the city lights connects to. Anybody know? Should I cut it once I splice it into the parking light wire? ANy info would be appreciated. Thanks
