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) |

I've had H4 55W for over a year - no relay and no problems. I'm pretty sure the relay is for the 100W bulbs. A direct circuit from the battery to the new relay, can be mounted in the front trunk near washer bottle or whatever, is recommended for the 100W. The old wires in the 914 were not designed with 100W in mind, so the bulb upgrade has to have its own dedicated circuits. I think the "Aaron Cox Blog" might have photos. I'm very happy with my 55W H4s + 55W Pilot fog/driving combo. (IMG:style_emoticons/default/beerchug.gif)

I've had H4 55W for over a year - no relay and no problems. Is there anyone out there with the electrical know-how to give a definitive answer though? I can imagine a situation where "one year with no problems" turns into "two years and a fried starter". Maybe that isn't realistic, I'd just like to be sure. |
