H4 Upgrade, Search was helpful, but still have a question... Options

[Lavanaut]

I just purchased a set of H4s with the 55 watt bulbs. I also ordered the powered relay that PP's site recommends. After searching the forum for information on the install, I'm left wondering: do I even need this powered relay if I'm going to stick with the 55 watt bulbs? Several posts make it sound like I don't. We're talking about a stock '74 2.0. Oh, and I did read-up on relays over at the12volt.com but am still unsure.

If I *do* need it, then I've got another question. I think I'd install the relay on the relay board in the spot labeled 'A' in Hayes, p. 128, Fig. 9.22...is that correct? Finally, and here my true newbie colors shine through, how do I get at the relay board? For all of my reading, I can't figure out where the thing is located (best guess is at/behind the fuse panel).

Hmmm...guess that's a 3-part question after all.

Thanks in advance, and happy Friday!! (IMG:style_emoticons/default/beerchug.gif)
