JH,
That's actually a capacitor. Porsche used them as noise filters for the ignition. (Ballast resistors were only used 64-68 and they were a square box, and the "intermediate unit" was used only in 69-70 and has three terminals.)
Second pic, I don't see a six pin connector. I see a pair of 14-pin connectors, a fuse box, three factory 1/4" fastons, pair of three-pin plugs and a relay socket.
The relay socket is for the warm-up regulator relay.
