H4 parking light bulb

[1983sccoupe]

Does anyone know how to wire the tiny bulb in an H4 housing that is for the european parking light. My 911 H4 euro headlight assemblies have a small socket near the main headlight bulb that is used for the euro parking light. Ie. when your parking lights are turned on, then this tiny little bulb in the housing makes the entire headlight lens "glow". I was wondering if there is a little harness to light these off of the existing power harness that terminates in each headlight bucket, or do I have to craft something?

Thanks..
