Do the quad round headlights have the same wiring as the dual seven-inch headlights?

I have a set of the quad round headlights and I am trying to plan out how I will wire them in my car. It appears that the only wires running out of these headlights are a ground wire and two wires together (red and green, I think)) that go into a single connector. I've heard that the seven-inch round beams can be swapped out fairly easily with these dual ones, and so I was wondering if the wires from both terminated in this same connector (perhaps the same for the sealed rectangular beams--1978-1985--as well?).

I am planning to remove my post-'86 Aero headlights and replace them with the quad rounds over my Christmas break. The wiring is not a direct swap (since there are no connectors I've noticed with these 9004 headlight bulbs), so I'm going to have to be splicing wires. Since I would already be cutting and splicing stuff, I figured that I might as well buy a relay kit and install that in the process. I would be purchasing the relay kit from Daniel Stern Lighting, and so I need to be able to tell him what kind of relay kit I would need.

It looks like I need the "top half" of a 9004 kit (the wires above the relay) and the "bottom half" of the dual sealed beams kit (the wires from the relay to the lights). It appears that the wiring for the quad sealed beams that Volvo used is identical to the dual sealed beams. I counted four wires--two in each connector. One wire, I would guess, is a high beam line (with the two high lights wired in sequence), and the other is for the single low beam (one light). Thus, the quad sealed beams would use the same kit as the Volvo dual sealed beams.

Additionally, it appears that Mr. Stern has already made a kit for this purpose--RIK-H4R. My upper wiring will still be designed for the (lower voltage?) 9004 bulbs, but the lower wiring will be for the (higher voltage?) sealed halogen beams. That kit seems to be designed expressly for my situation.

Is that the relay kit that I need? Am I right about the quad sealed beams using the same method of wiring as the dual sealed headlights? Input, particularly from those experienced with the quad headlights, would be greatly appreciated!
