It is clear that on the updated glow plugs the + voltage is a series circuit and the grounds are parallel circuits.
The individual wires to each glow plug are to make life easier for the harness maker. Inside the glow plug relay, they are all common with each other, electrically identical to simply taking all 4/5/6 wires and tying them together with a wire nut. It is a parallel circuit, the only thing "series" about it is the relay switching B+.
