Fog light install questions
In this video, at 5:25 you see a c5 z06 with these lights.

I've located the exact same lights the C5R's used, not concerned with mounting really. My questions are about wiring. I'd like to use a factory fog switch, so, how will I need to wire them up? They use a 100w H1 halogen bulb. Relays? I'm sure I'll need them. Wire gauge? Ground points?
I know there was a kit available in the past, but is no longer made. I know it's definitely possible to use these lights. Something different! Something to pay homage to the C5R!
Thanks! Dylan

I do realize I'll be giving up the chance at a nice ready to install kit though...

A few years back I sent them an email inquiry and got no response, but the web site still seems to be there.

The Oscar SC is a 6" light, The Oscar is a 7" light. Measuring the front plate area showed it was ~14 1/4" long. The 6" fits with a little room to spare. According to the guy I spoke with about the kit on that site and some pictures he sent me of the install, to fit the lights they have you still do need to cut into the foam behind the bumper.
I'd like to produce a nice, clean factory looking harness also.
I've never wired lights before. What would be the safest, simplest way to do so? Relays? Fuses? Wire gauge? I'll just use a standard toggle switch.

Tell me if I'm understanding. What you describe would allow me to have high beam and the aux lights on at the same time. When there is oncoming traffic simply turning the high beams off via the factory high beam switch would also turn the aux lights off? And of course just switch to low beam only? The aux lights would also have their own switch to operate independently at any time?

As to the wiring, 12 gauge will do. You'll need a 30 Amp fuse and the relay of course. As I recall, the switch is rated at 25A. Talk to Daniel Stern. (danielsternlighting.com) He will set you down the correct path; he can advise you about the correct relays, wire gauge, fuse, and how to tap for power. Likely he'll suggest directly off the battery posts.
The z06s are all set up powered for a fog light switch. It doesn't matter if you're gonna use cheep Chineee junk or OEM-quality goods. The built-in OEM harness to the switch port (where the OEM dual switch fits) are good enough to withstand your needs. You'll need to find a dual switch--fog light and trunk release combined--the common z06 single-function trunk release is installed in ALL domestic models; those built for overseas export had the dual switch installed and included E-code headlights, not the 27w bling lights.
What all domestic z06's are missing is the wiring from the fog lights themselves to power. You'll need a beef'd fog light harness. The OEM domestic harness intended for US DOT fog lights is not heavy duty enough to withstand your CIBIE power needs. You can build the harness yourself. I paid for a sample to copy with much heavier gauge wire, so you're getting this free.
I didn't know jack squat about wiring, soldering and 12v power, but with Daniel Stern, the schematics and help from a former member, Dadaroo (Bless you, Sam) this project proceeded fairly painlessly as far as the wire cutting, connecting and prep went. There are two guides that both essentially show you how to wire correctly. Search the 'Net for "PIAA 34085 fog light harness instructions.pdf" and an Acrobat Adobe file should be easily found that you can print. It's essentially a graphic picture. The other guide is attached below:
Study those for a while before you talk to Stern so you can converse coherently with him. He is better than ANY CF vendor; he'll tell you the truth about Chineee junk fog lights, he emphasizes building for safety, durability and longevity. Your bias towards CIBIE's shows you're interested in sheer quality, so Stern's the man to talk to because he's rigid and uncompromising when it comes to 12V electrical circuitry.
If you've got an electrician friend who'll help you, here's the OEM Service Manual schematic:
DO NOT REMOVE THE FUSE BOX IN THE ENGINE AND SPLICE INTO THE PURPLE WIRE UNDERNEATH IT FOR 12V POWER. MORE THAN ONE CorvetteForum VENDOR AND SEVERAL DIYers RECOMMEND THIS METHOD for splicing your harness to power. IF YOU HAVE TO TAP THE FOG LIGHT FUSE FOR POWER, USE A 10A FUSE TAP and do it properly. Tapping the purple wire creates a fire hazard; you'd be tapping what is probably a 16-18 gauge wire with a 12 gauge (or minimally, a 14ga) wire and the power draw could be disastrous. Lots of guys do it this way, but that doesn't make it safe. A fuse tap is easy and clean. Sure, 12ga is "overkill" but you want wire that won't ever get brittle from the heat of constant or protracted use. An extra 20-30 cents a foot... why skimp?
Good luck.

The wiring diagram I drew up was what I understood as how to do it based on how he explained it to me. As far as tapping into the high beam switch he told me some 16 gauge would do, as it's only to signal the relay to power on the cibies' when the high beams are switched on. 12 gauge for power and grounds throughout the rest of the harness. He also recommended a switch in cabin to interrupt the relay ground so I could use the high beams without the cibie lights if I wanted.
I plan on powering through a 20A fuse off of the battery post. Grounding to factory ground points of course.
I think I'll be contacting Daniel Stern as you've suggested for even more input and insight.


I agree, it is a lot of work, but I love projects like this. I'm more excited to do the work than to have the finished product haha.
I'll keep you all posted here, and take pictures of course.
Here's a picture provided to me of what the full kit once was from aardvark international.
I'll have to drill into the frame to mount the T's.
The lights and T's should be shipping soon!
Still need to find some aluminum and someone to cut it for me.
I spoke with Daniel Stern, and he gave his blessing for my wiring plans. Can't wait to get it going!
