I'm curious about this also. I just bought some PIAA 1100x's and I'd like to have them on with the headlights.
I bought the replacement piece for the Z (to add the fog light switch) but I want the PIAA's to stay on when I have the high beams on. I'm sure someone has figured out how to wire this up so it will work.
Technically, they are fog lights. Since you wouldn't drive with your high beams in fog, that's why they aren't on with the high beams.
Well, they are wired as fog lights on the C5 and I think that's really the problem with the PIAAs. The are really driving lights and should work in conjunction with the brights instead of the low beams. I wouldn't consider a 35% beam to be for fog. See this link.
I've done driving lights on several cars that would work in conjunction with the high beams, but you have to do some additional wiring. Not sure how you'd use the Fog switch on the C5.
On my Fbody, I wired a relay to sense the high beam voltage for the driving lights to be on. In other words, with the switch for the aux lites on, the hightbeam switch actually turned them on and off.

I figured there'd be problems using the fog light switch. I should have just wired the lights up independently and saved the $30 for the switch.
I have a relay that will allow the bright lights to work in conjunction with the low beam. I don't know if the PIAA lights will remain on when bright beams are turned on. I haven't had the time to install it yet but will let you know the results when it's installed. I had asked this question about having both hign/low on at the same time but I get this "are you nuts?" responses. If common sense is used, a safe driver do not turn their high beam on at oncoming traffic or at close distance from behind. Having both beams on at the appropriate time, IMHO will improve safe driving. We all know the stock lights are not that great.

I appreciate it.
There are times when the more light you have, the safer it is. I live outside of Valley Forge Park in PA and there are deer all over the place. Most of the roads don't have street lights and at night it is hard to see what's in front of you. Having the high beams on plus the PIAA's would help. At least until I can find a nice, high-quality HID replacement for the stock lights.

My brother bought a kit that did this for his Chevy pickup. I think Painless wiring makes it for about $40. Works great.
When I put in the PIAA's I also installed a new wiring harness and a switch. I can turn them on anytime the key is on. I did not want them to operate like the fog lights.
Tuan Le a forum vender had the wiring diagram in an older post. His new post does not have the info, but I'll bet he can get it for you, or do a search on Piaa's. The post was there until recently. If I remember correctly, the relay trigger wire is connected to a different location.
srsjuju,
I had done this last year and, with Mark's help, I am able to run High beam, Low beam and PIAA's all at the same time or any combination of the above. Not that difficult at all. You will need 2 of the Radio Shack relays and 2 switches. If interested, I still have the wiring diagram...PM me.

Let me know how that relay works for you
.
Just to report back that the relay I had installed works great. Both high beam and low beam stay on when high beam switched on. My PIAA will not stay on though. It was an easy install. One wire to the "+" battery post and one ground wire to car frame. one wire tap to high beam and one tap to low beam from the relay. That's it.
