I'll have to snap some shots of the relay job I did on the Quantum, I'm rather proud of it. Dedicated power, dedicated ground, and short wiring runs for each.
I'm stuck with stock sealed beams until I can free up some more cash (Come on, semester start! Bring my money back in!), but the relays are mounted beside the headlight pair each feeds, so I didn't have to loop away or cut up the stock wiring. I bent up some little sheet metal shields to keep water and dirt from getting in them, and they're not stuffed up somewhere where there is no air circulation to keep them cool so they should last a long time.
