I wanted to post an update on what I ended up doing. I ended up making my own wiring harness using two 5 prong relay pigtails (removed the center wire since it is not used) rather than having 4 female spade connectors for each relay.
These are the instructions I used:

I mounted the relay's in the front corner of the inner fender on the d/s. There is a small flat section on the inner fender slightly forward from the windshield washer fluid tank where I mounted a fuse block. (chose to go this route rather than an inline fuse for each relay) I pulled the power from the junction block on the firewall to the fuse block using 12 gauge wire. Routed it from the fuse box, inside the inner fender, wrapped in wire loom, and then along the fire wall to the junction block.
As described in the instructions, I made sure to cut the correct light brown wire as there are two of them that go into the low beam headlight. One goes to the switch and other runs across to the p/s headlight. That's where the extra prep time comes into play for me. Kind of like the "measure twice, cut once" concept. I'll take some pictures tonight and add them to this thread for reference as needed.
So far, I still have the stock headlights installed and stock connectors. Mine are getting a bit brittle and showing signs of age so I will replace those as well with some heavier gauge wire. I can see a noticeable difference in the brightness with just the relays. I'm replacing the headlights with H4 glass lenses and adding the 90/100W bulbs. I have these same bulbs on my 1975 droF and the visibility is AMAZING!
For anyone who has not done this upgrade, I highly recommend it.
